Fees slipping below cost without anyone noticing. Variations done but never priced or invoiced. Timesheets scattered across spreadsheets. Nobody quite sure which drawing is current. If that sounds like your practice, the problem usually isn’t your team. It’s that generic project tools were never built for how an architecture firm actually delivers work.
At ByteGears we build custom architect project management software that fits your practice, instead of asking your practice to bend around the software. Our UK team builds bespoke systems around the workflows you already run, mostly for British architecture practices and construction consultancies between 4 and 200 people. The aim is straightforward: structure projects around RIBA stages, keep fees and profitability visible, and cut out the re-keying, without forcing a rewrite of how you work.
Where off-the-shelf tools tend to break down
Most practices try generic project software or a SaaS practice management tool first. A few problems come up again and again:
- RIBA isn’t native. Generic tools like Monday.com, Wrike or Asana have no concept of the RIBA Plan of Work, so teams rebuild stage 0 to 7 by hand and end up back in spreadsheets. Even some architecture-focused tools only partially support it.
- Fee models are rigid. Most platforms assume a single billing approach. Percentage fees, staged milestones, time-and-cost caps, equity shares or performance-linked arrangements either don’t fit or need expensive customisation.
- Variations are hard to track properly. The real workflow runs design change to client approval to consultant pricing to budget adjustment to invoice line. Off-the-shelf approval workflows rarely match that, so variations get done and never billed.
- Per-user pricing climbs as you hire. SaaS bills scale with headcount and most vendors raise prices each year. The tool gets more expensive precisely when the practice is growing.
- Accounting sync is shallow. Xero and QuickBooks integrations are often one-way or batch-processed, so WIP and invoicing still need manual reconciliation.
- BIM and CAD links are weak. Almost no project management tool exchanges data meaningfully with Revit, so cost and schedule impacts of design changes get worked out separately.
So people patch the gaps by hand. Spreadsheets to track what the software won’t. The same numbers re-keyed into accounts. The result is lost billable hours, version control headaches, and a team stitching together half a dozen tools that don’t talk to each other.
When SaaS is genuinely enough
We’d rather be honest about this. A small single-office practice with a straightforward fee model, light variation work and no integration needs beyond Xero is usually well served by an off-the-shelf tool. If that’s you, a bespoke build is hard to justify yet.
Custom software starts to earn its place when the friction is real: non-standard fee structures, complex variation and change control, multi-office or shared-staff coordination, specialist compliance such as heritage or conservation approvals, deep BIM integration, or a per-user SaaS bill that has quietly become one of your larger overheads. If two or three of those apply, the maths and the day-to-day experience both start pointing the same way.
How we approach it differently
We start with your process, not the code
Before anyone writes a line of code, we map your RIBA delivery, your fee and variation workflows, your client approval steps and how you control documents. Inadequate process mapping is the single most common reason software rollouts fail. We’d rather spend the time upfront.
Built around RIBA, or around your model
Projects are structured on the eight RIBA stages as a first-class concept. Time, fees, budgets and reporting all line up to the right stage. If you run a modified or hybrid delivery process, we build that instead.
You pay once and own it
Instead of a SaaS bill that never stops and grows with headcount, you get a system you own outright: source code, data and all. No per-user licensing, no annual price rises, no charge to export your own data.
It connects to what you already use
- Xero, QuickBooks and Sage for invoicing and WIP, with a proper two-way sync
- Slack or Microsoft Teams for approvals and alerts
- OneDrive, Google Drive, Dropbox or Box for documents
- Revit and CAD file linking where it earns its place
- A documented API so future integrations don’t depend on a vendor
UK compliance is built in
- RIBA stage structure and stage-aligned reporting
- UK GDPR safeguards, with UK hosting or on-premise deployment where data residency matters
- A full audit trail of changes, supporting the six-year records retention auditors expect
- Role-based access and encrypted storage as standard
It grows with you
We deliver a core system first, then add modules as you need them: variation management, resource planning, a client portal, consultant management, design review tools. You decide the order and the pace.
What we usually build
The system manages the entities a practice actually runs on: projects and RIBA stages, clients, staff and rates, timesheets, tasks, variations, consultants, budgets and invoices, with the integrity rules that keep the data trustworthy.
1. RIBA-staged project workspace
Every project structured on RIBA stages 0 to 7, with deliverables, approval gates and fee milestones tied to each stage.
2. Time logging and timesheet approval
Time logged against the correct project and stage, marked billable or non-billable, with approval workflows and a mobile option for staff logging time on site.
3. Fee and budget tracking
Budgets by stage with burn-down against actuals, and alerts when a project gets close to its agreed limit. Profitability visible by stage, project, client and consultant, not just at the headline level.
4. Variation and change control
The full workflow: log the change, price it, route it for approval, adjust the budget and fee, and push it through to an invoice line. Variations stop falling through the cracks.
5. Resource scheduling
Visual team allocation across projects that accounts for leave and availability, flags double-booking and shows where capacity is tight or idle.
6. Project dashboard and reporting
A live view of every active project: stage progress, budget burn, upcoming milestones and a RAG status. Stage reports, client updates and partner-level overviews generated without rebuilding them by hand.
7. Invoicing and accounting sync
Invoices assembled from logged time, fees and approved variations, with a two-way sync to your accounting package rather than a manual export.
8. Document control
Version-controlled storage for drawings, specifications and contracts, with approval workflows so everyone is working from the current version.
9. Client collaboration portal
A secure space where clients review drawings, leave feedback, approve work and see where the project stands, without a separate data silo.
10. Consultant and subcontractor management
Track engineers, M&E, surveyors and other consultants: scope, rates, subcontract terms, insurance certificates and performance, with role-specific approval chains.
How the build works
Phase 1: Discovery and planning (1-2 weeks)
Process mapping sessions and user interviews, working out where the real pain is, defining requirements and confirming what needs to integrate with what.
Phase 2: Core build (around 8-12 weeks)
The MVP that delivers value early: RIBA-staged projects, task and milestone management, time logging and approval, budget-versus-actuals tracking, a status dashboard and basic invoicing. Agile sprints, a demo every two weeks, your feedback folded in, security considered throughout.
Phase 3: Financial integration and rollout (around 4-8 weeks)
Variation workflows, profitability reporting and the Xero or QuickBooks sync. User acceptance testing, data migration, a pilot on one or two live projects, then full rollout with the old system retired.
Phase 4: Advanced modules and support (ongoing)
Resource planning, client portal, consultant management and deeper reporting added as you need them. Role-specific training, user guides for your setup, six months of support included, and an optional retainer after that.
Most practices reach a usable core system in three to four months. Heavier integrations, multi-office consolidation or large historical data migrations extend that. We’re honest about scope upfront so the timeline holds.
What it costs
Custom development costs more upfront than a SaaS subscription. It is not the right call for every practice, and we’ll say so if it isn’t.
Where it does add up is total cost over time. SaaS bills scale with every member of staff and tend to rise each year, before you count setup, integration fees, paid support and the cost of being locked in when you want to leave. A bespoke system is a one-off build plus modest hosting and support. For a mid-sized or larger practice, the five-year total often lands below per-user SaaS, and you finish owning the asset rather than renting it.
The price depends on how many users you have, how much needs to integrate, how detailed your reporting is and how much mobile access you need. We give you a real number and a five-year comparison after a free consultation, once we understand what you actually need. Most SME architecture practices spend somewhere between £15,000 and £45,000 for a full system.
What you get either way: full ownership of the code and data, no per-user pricing, and no vendor deciding when prices go up.

Common Questions About Architect Project Management Software | Custom UK Solutions
How does custom development cost compare to SaaS practice management tools?
Custom software is a larger upfront cost and SaaS looks cheaper on day one. The gap closes as you grow. Per-user platforms charge every member of staff, every month, and most raise prices each year, so a 30-person practice can be paying a serious annual bill before counting setup, integration fees and paid support. A bespoke system is a one-off build plus modest hosting and support, and you own it. We give you a real five-year comparison during the consultation rather than a vague promise.
What's the typical development timeline?
Most practices get a usable core system in three to four months: RIBA-staged projects, time logging and approval, budget tracking and a status dashboard. Financial integration, variation workflows and reporting usually follow over the next few months. We deliver in stages so your team is using something real early, rather than waiting for a single big launch.
Do you support the RIBA Plan of Work?
Yes. We build projects around the eight RIBA stages as a first-class structure, not a workaround. Time, fees, budgets and reporting all line up to the stage they belong to. If your practice runs a modified or hybrid delivery model, we mirror that instead.
Can you handle non-standard fee structures?
Yes, and this is often the main reason practices move off generic tools. Percentage fees, lump sums, time-and-cost, staged milestones, equity or performance-linked arrangements, and variation pricing can all be built into the system. Off-the-shelf software usually forces one fee model on you.
Can you integrate with our existing systems?
We commonly connect to Xero, QuickBooks and Sage for invoicing and WIP, plus Slack or Teams for alerts and OneDrive, Google Drive or Dropbox for documents. Where it adds value, we can link to Revit and CAD files so design changes feed into schedules and cost estimates. We build a proper two-way accounting sync rather than the one-way batch exports many SaaS tools settle for.
What about data security and compliance?
Solutions include UK GDPR safeguards, role-based access, encrypted storage and a full audit trail of changes. We can host data in the UK and offer on-premise deployment where data residency matters, which SaaS vendors often cannot guarantee. Audit trails also support the six-year records retention auditors expect.
Do you provide training and ongoing support?
We deliver role-specific training: a short session for partners on dashboards and reporting, more detailed sessions for project managers and finance, and a quick walkthrough for staff logging time. You get user guides written for your setup, six months of support included, and an optional maintenance retainer after that. You own the code throughout.
