A quote that takes twenty or thirty minutes to put together, then sits in someone’s inbox for two weeks waiting on a sign-off, is costing you deals. So is the spreadsheet your senior estimator keeps “for the real numbers” because the SaaS tool you bought can’t apply your margins properly. If your team copy-pastes line items between files, retypes prices from a supplier email, or quietly works around the software because it doesn’t fit how you actually quote, the tool isn’t earning its keep.
We build custom quoting and estimating software for UK businesses that have outgrown that. The software is shaped around how you price, approve and send work, connects to the accounting and CRM systems you already run, and stays yours to change as the business does. We’re a small London consultancy, and we mostly work with SMEs whose pricing logic is genuinely particular, not the kind any off-the-shelf product handles cleanly.
Why off-the-shelf quoting software usually disappoints
The demo looks great. Three months later half your team has invented Excel workarounds because the tool can’t handle your pricing rules, your approval chain, or the way you bundle items for a particular client type. We’ve seen this play out enough times that it’s stopped being surprising.
The usual sticking points:
- The workflow is fixed. Most tools assume a linear path: draft, one approval, send. If your business needs conditional routing, the tool fights you.
- The pricing engine is shallow. List price, discount percentage, simple volume tiers. That’s fine until you need regional labour rates, cost-plus modelling, supplier surcharges or commission clawbacks.
- Per-seat costs creep. Add salespeople and estimators and the subscription climbs. A twenty-person team on a per-user CPQ tool can easily reach £12,000 to £25,000 a year once integrations and support are included, and renewal prices rarely move down.
- Customisation stops at branding. Logos and a few custom fields, then you’re filing feature requests into a vendor backlog you don’t control.
- Integrations are an add-on, not a given. It may sync to Xero or HubSpot through a paid connector, or only through Zapier with a one-way lag, and it almost certainly won’t talk to your older in-house systems.
- The data is hard to get back out. Tightly integrated platforms make their value out of being expensive to leave.
So people retype data, export to spreadsheets to do the real calculation, then paste numbers back in. That isn’t automation. It’s a more expensive version of the spreadsheet, with an audit trail you can’t fully trust.
What we build instead
When we build for you, the brief starts with how your team quotes today, not with a feature list. The point is software that matches your process closely enough that nobody needs a side spreadsheet.
- Your pricing logic, encoded properly. Discount tiers, margin floors, cost-plus models, regional rates, customer-specific terms and bundle pricing applied automatically, so no rep can quote below the floor and no approver has to check the maths by hand.
- Approval routing that matches your rules. Conditional logic, not a fixed chain. “If margin is under 15%, escalate to finance.” “If the quote is over £50k for a new customer, require a second sign-off.” “If it has been sitting three days, chase the approver.” All built in, with timestamps and approver identity logged.
- Integrations as part of the build. An approved quote becomes a draft sales order in Xero, Sage or QuickBooks; customer records flow to and from your CRM; cost and stock data is pulled live where the source system allows it. Older or bespoke systems get a dedicated integration layer.
- One price for the build, not a per-seat meter. You add users without the bill moving.
- Yours to extend. New service line, new pricing model, new integration: changes are built in weeks, not waited on for quarters.
- Support from the team that built it. You speak to the people who know the code, not a ticketing queue.
Features we typically include
Every build is different, but these are the capabilities most clients end up wanting:
- A quote builder with editable line items, units of measure, and automatic totals, tax and discounts.
- Rule-based pricing covering discount tiers, margins, cost-plus calculations and product bundles.
- A template library for the quotes you send most often, with version control and expiry dates so customers never see two live versions.
- Multi-level and conditional approval workflows, with escalation when a quote stalls.
- Customer history in the quote view, so reps see previous orders, pricing tier and payment terms.
- Quote-to-order conversion that pushes approved work straight into your accounting system.
- A reporting dashboard for win and loss rates, average sales cycle, margin by estimator or customer, and where discounts exceeded policy.
- E-signature capture and a customer portal for viewing and accepting quotes.
- Mobile-friendly quote creation, so a field rep can price a job on site rather than back at the office.
- Role-based access, so junior staff can draft but not send.
- Encrypted storage and a full audit trail on every quote: who created, changed, approved and sent it.
- API and webhook connections to your accounting, CRM, inventory and supplier pricing systems.
How we run the project
A typical engagement runs in four stages:
- Discovery and planning, usually 2 to 3 weeks. We sit with your estimators and approvers, document how quoting works now, and agree what the software needs to do. This is also where we map your pricing rules and approval matrix in detail, because that’s where most of the real complexity lives.
- Development, usually 6 to 10 weeks. We build in short cycles and show you working software along the way. We tend to ship a focused first release, covering quote building, pricing, PDF output and core approvals, then layer integrations and reporting on top rather than enabling everything on day one.
- Testing and deployment, 2 to 4 weeks. QA, user acceptance testing, and data migration: customer master data, your product and service catalogue, the approver list, and historical quotes if you need the audit trail. Then go-live.
- Training and support, ongoing. Hands-on sessions, written documentation, and a support arrangement sized to how much help you actually need.
Most projects land in the 3 to 5 month range. Heavier integration with legacy ERP or inventory systems can push it longer; a simpler internal tool can be faster. Phased rollout matters here. The most common reason these projects struggle is switching everything on at once with no internal owner, so we plan around a clear first release and a named lead on your side.
What the investment looks like
Custom development costs more upfront than a SaaS subscription. The comparison changes over time. A per-seat CPQ tool for a mid-sized team often settles into the £12,000 to £25,000 a year range once integrations and premium support are added, and enterprise platforms go well beyond that. A bespoke build is a one-off project cost plus modest hosting and support, with no per-user charge.
A few practical points:
- You know what the build costs before you commit. Subscription pricing tends to drift upwards on renewal, and you pay for tier features other companies happened to want.
- The maths usually starts to favour custom around the two to three year mark, sooner once you count the workarounds and lost deals the SaaS tool was causing.
- The software is yours. If your business changes, you change the software, and there’s no vendor lock-in or export fight if you ever move on.
- The return shows up as time saved per quote, fewer underpriced jobs going out, and shorter approval cycles.
We always start with a free consultation to look at your actual situation. If a SaaS product would genuinely serve you better, we’ll say so plainly.
Where bespoke makes sense, and where it doesn’t
Custom software isn’t the right answer for everyone. If your quotes are linear, your pricing is fixed list prices with simple volume discounts, one manager sign-off is enough, and standard Xero or QuickBooks integration covers your accounting, an off-the-shelf tool will likely serve you well for less money. We’d rather tell you that than sell you a project you don’t need.
Bespoke earns its place when:
- Pricing logic is genuinely complex: cost-plus with regional labour rates, supplier-specific surcharges, commission structures or customer-segment pricing.
- Approval routing is conditional, with margin thresholds, value bands or escalation rules.
- You run multiple locations or entities, each with its own cost centres and approval hierarchy.
- You need tight integration with a legacy ERP, a custom inventory system or a proprietary cost model that no SaaS tool has a connector for.
- Your industry needs a particular data model, such as construction takeoffs, manufacturing BOMs or field-service crew costing.
- You face audit or compliance demands beyond GDPR, such as ISO 9001 document control, CIS, or Making Tax Digital record-keeping.
Sectors we build quoting software for
The pattern repeats across industries, but the specifics vary:
- Construction: labour and materials estimates for builds, extensions and renovations, with regional cost variation, multiple supplier quotes, takeoff data and multi-stage bid approvals.
- Manufacturing and job shops: BOM-driven quoting with cycle times, tooling, material surcharges and outsourcing, plus the heavier approval an engineer-to-order job needs.
- Field service: electricians, plumbers and HVAC engineers quoting on site, balancing standard pricing against site-specific work, with invoicing and payment links built in.
- Professional services and consulting: day-rate and man-hour estimating, utilisation-based pricing, expenses and travel lines, partner commission splits.
- Retail and wholesale: B2B bulk quotes with customer-specific pricing, tiered discounts and inventory-aware availability.
- IT and managed services: multi-year contracts mixing recurring revenue with one-off project costs, and approval for larger deals.
- Print and bespoke manufacturing: multi-format estimating with ink, substrate and material cost tracking, and the fast turnarounds the work demands.
- Facilities management: maintenance contract pricing with SLAs and recurring service lines.
In each of these, the pricing logic is rarely simple, and software that tries to serve every industry ends up not quite right for any of them.
Common Questions About Custom Quoting and Estimating Software
How does custom development cost compare to SaaS quoting tools?
A custom build is a larger upfront cost than a monthly subscription, but the comparison shifts over time. Per-seat CPQ tools for a 20-person team often run £12,000 to £25,000 a year once you add integrations and premium support, and that figure tends to climb on renewal. A bespoke build is typically a one-off project cost plus modest hosting and support, with no per-user meter. For most teams the maths starts to favour custom somewhere around the two to three year mark, and you own the software outright either way.
What's the typical development timeline?
A focused first release, covering quote building, pricing rules, PDF output and one or two approval levels, usually takes six to eight weeks. Adding accounting and CRM integration, advanced approval logic and a reporting dashboard typically adds another four to eight weeks. Most full builds land in the three to five month range; heavy integration with legacy ERP or inventory systems can push it longer.
How do you handle updates and changes after launch?
You own the code, so you are never waiting in a vendor's feature backlog. We offer support arrangements sized to how much help you actually need, from occasional changes to a standing retainer. Most clients budget for a couple of meaningful updates a year as new service lines, pricing models or integrations come up.
Can you integrate with our existing accounting and CRM systems?
Yes. Common connections are Xero, Sage and QuickBooks on the accounting side, and HubSpot, Salesforce or Pipedrive on the CRM side, plus inventory and supplier pricing feeds. We build these as part of the project using documented APIs or webhooks, so an approved quote can become a draft sales order without anyone re-keying it. Older or in-house systems are handled with a custom integration layer.
What about data security and compliance?
Builds are UK GDPR-compliant by default, with encryption in transit and at rest, role-based access and a full audit trail of who changed, approved or sent each quote. We host on UK or EU infrastructure so quote data does not leave the region. Where you operate under ISO 9001, CIS or Making Tax Digital, the approval trails and document retention are designed around those requirements rather than bolted on.
When is off-the-shelf quoting software the better choice?
If your quotes are linear, your pricing is fixed list prices with simple volume discounts, and one manager sign-off is enough, a SaaS tool like Jobber, Tradify or PandaDoc will likely serve you well and cost less. Custom makes sense when pricing logic is genuinely complex, approval routing is conditional, you run multiple locations or entities, or you need tight links to legacy systems. We will tell you honestly which side of that line you sit on.
Do you provide training for our team?
Yes. Estimators and salespeople usually need two to four hours on quote creation and approvals, approvers an hour or two, and finance or ops a longer session on configuration and reporting. Training and written documentation are part of every project, with refresher sessions available later.
