A spreadsheet forecast that never quite matches what’s in the bank. A cash position you only piece together properly at month-end, by which point the decision you needed it for has already been made. Most businesses outgrow their cash flow process the same way: more bank accounts, a second legal entity, longer customer payment terms, and a forecast that’s always a step behind reality.
ByteGears builds custom cash flow management tools for UK businesses. Instead of bending your finance process to fit a generic product, we model the way money actually moves through your business: how you bill, when customers pay, what timing rules your sector imposes, and where the cash pinch points really are. The result is a clear view of your position today, a forecast you can trust, and the controls to act before a shortfall becomes a problem.
We’re a UK consultancy focused on automation for small and mid-sized businesses, so we’ll also be straight with you: if your needs are simple, a SaaS tool is the cheaper answer, and we’ll say so.
Where off-the-shelf cash flow tools fall short
For a single entity with standard invoicing and payment terms, tools like Float or Agicap do the job well. The problems start as a business gets more complex. These are the things we hear most often from finance teams before they move to a custom build:
- Generic forecasting logic. SaaS tools project from historical averages plus known invoices. They don’t model construction retention, subscription revenue recognised over a contract term, supplier lead times, or insurance reimbursement delays, so the forecast quietly drifts from how your cash actually behaves.
- Weak multi-entity consolidation. Standard tools assume a simple parent-child structure. Inter-company eliminations, franchise remittance schedules and joint ventures break the templated logic, and you end up consolidating in a spreadsheet anyway.
- Rigid approval routing. Most products only support linear approval. Conditional rules, such as requiring CFO sign-off above £50,000 or a project manager on project-related spend, usually aren’t possible without custom work.
- Per-seat costs that climb. At £50 to £150 per user per month, a growing finance team becomes an expensive line item, and three-year contracts make it hard to leave if the tool disappoints.
- Integration friction. Bank feeds lag 24 to 48 hours, multi-source feeds double-count transactions, and standard connectors don’t map your non-standard revenue and cost categories.
- Compliance gaps. International products handle Making Tax Digital and VAT awkwardly, and US-hosted SaaS can be a problem where you need UK data residency.
The usual result is a pile of manual workarounds, a forecast nobody fully trusts, and insight that arrives after the fact.
What we build instead
A ByteGears build starts with how your business actually earns and spends, then puts that logic into software you own:
Forecasting that matches your business We build the timing rules your sector lives by into the forecast itself: retention release dates, milestone billing, deferred revenue, grant drawdowns, seasonal demand. Your forecast reflects reality, not a generic average.
A real-time view across every account One consolidated cash position across all your bank accounts and entities, with drill-down from any total to the underlying transactions, so you can explain a variance instead of guessing at it.
Pay once, own it A one-off build instead of a per-seat fee that grows every time you hire into finance. You hold full rights to the software, with no vendor lock-in and no three-year contract.
Connected to what you already run We link to your accounting software, ERP and bank feeds so figures line up without re-keying, and we handle the awkward parts: feed lag, deduplication and GL mapping.
UK compliance built in VAT categorisation and MTD-ready reporting, an immutable audit trail, and UK hosting where data residency matters. Where your sector adds rules, from FCA to CQC, we build to suit.
Room to grow Start with a focused first release and add entities, modules and integrations as you need them. No painful migration, no rebuild from scratch.
A team in your time zone Our UK team handles implementation and ongoing support during UK business hours, which matters most during month-end close.
Features and modules we build
We scope each build to what you need, but these are the modules UK finance teams ask for most:
Cash position dashboard A live view across every bank account and entity, with receivables and payables ageing, working capital metrics, and the KPIs that matter to you. Drill from any figure down to the source transaction.
Rolling forecast A 13-week and longer-range forecast that updates from actuals as they land, with variance analysis showing forecast against actual and the reasons behind the gap.
Scenario modelling Best, base and worst-case planning so you can see how a hiring decision, a bulk stock purchase or a slow-paying client would hit cash before you commit.
Bank feeds and reconciliation Open Banking feeds with automatic categorisation and matching of transactions to invoices and bills, with deduplication between bank and ledger and a human review for the cases that need it.
Invoice and bill tracking AR and AP ageing tied into the forecast, so known future cash events shape the projection rather than sitting in a separate report.
Approval workflows Conditional and multi-level routing built to your rules, with escalation when an approver is unavailable, and a full record of who approved what and when.
VAT and MTD reporting VAT categorised by transaction type, liabilities tracked, and upcoming payment dates shown on the dashboard so a VAT bill never lands as a surprise.
Custom reporting Cash flow statements, liquidity and working capital reports, and forecast-accuracy tracking, in your own formats and delivered automatically to the people who need them.
Mobile access A secure, responsive view of the cash position and approvals for people away from the office.
Roles and audit trail Fine-grained permissions plus an immutable activity log, so staff see only what their role needs and every change is traceable for audit.
Configurable alerts Notifications for cash thresholds, overdue invoices or transaction patterns that look off.
How we deliver
Our process keeps the build close to what you need and keeps disruption low:
Discovery and planning (2 to 4 weeks) We map your current cash flow process with your finance team, identify the data sources to bring in, and agree what good looks like. Honest data hygiene matters here: a forecast can only be as accurate as the historical data behind it, so we look at chart-of-accounts structure and categorisation early.
Development (8 to 12 weeks) Our UK developers build on modern frameworks and show you working software regularly so you can steer it. We often deliver a focused first release first, a single-entity dashboard with a rolling forecast and two or three bank feeds, then add consolidation, approval workflows and wider integrations in a second phase.
Testing and deployment (2 to 3 weeks) Thorough QA including user acceptance testing, then a phased go-live. We usually run the new system in parallel with your existing process for a short period so forecasts can be checked against actuals before you rely on them.
Training and support (ongoing) Role-based training for everyone who uses it, plus 12 months of support and updates, with optional packages after that.
Most projects run 3 to 6 months depending on complexity. The biggest causes of delay are scope creep mid-build and legacy ERP connections taking longer than expected, so we plan integration work carefully and keep the first release tight.
Cost and ownership
A custom build is a larger cost up front than a SaaS subscription. The trade-off is what you get for it over time:
- A one-off build instead of a per-seat fee that climbs every time you hire into finance
- Full rights to the software, so no vendor lock-in and no three-year contract to escape
- No exposure to USD or EUR pricing swings, and no surprise charges for premium support, extra integrations or API overages
- No forced upgrades that break your customisations
- Treated as a capital asset rather than an ongoing operating cost
It’s worth being clear about the trade-off the other way too. SaaS wins on speed and low entry cost, and for a simple single-entity setup it’s the sensible choice. A custom build makes commercial sense once per-seat costs add up, once you’re consolidating multiple entities, or once your sector’s timing rules mean a generic forecast is never quite right.
We give you a fixed-price proposal after a free consultation and requirements analysis. Most SME builds land between £15,000 and £50,000, broadly comparable to several years of premium SaaS for a mid-sized finance team, with the difference that you own the result.
Industries we work with
The clearest case for a custom build is sector-specific timing that generic tools can’t model. A few examples:
Construction Retention clauses where the client holds 5 to 10 percent until project close, milestone-based billing, and subcontractor payment timing. We build retention-aware forecasting so held-back cash and its release date are visible, not buried.
Professional services and consulting Project-based revenue, the gap between work done and invoice raised, and high DSO. We forecast cash by project completion date and billing rate, and track DSO by client segment so slow payers stand out.
SaaS and subscription businesses Revenue recognised over a contract term rather than at invoice, churn, and long sales cycles. We model MRR and ARR alongside cash runway, with deferred revenue and cohort-based projections that simple tools can’t represent.
Retail and ecommerce Cash tied up in stock, tight conversion cycles and sharp seasonal swings. We tie inventory ageing into the forecast, consolidate revenue across online and physical channels, and model scenarios for bulk stock purchases.
Manufacturing Long supplier lead times, raw material cost variance and customer payment delays that strain working capital. We model the cash impact of lead time changes, bulk material buys and supplier payment terms.
Healthcare and medical services Insurance reimbursement delays, patient co-pays and claim cycles. We integrate claim status into the forecast so reimbursement timing shapes the projection rather than guesswork.
Non-profit and grant-funded organisations Restricted versus unrestricted funds and unpredictable grant revenue. We forecast against grant milestones and donor pledges instead of standard invoicing.
Property management Rental income cycles, maintenance reserves and refurbishment costs, with cash views by property or portfolio.
Every build keeps the core cash flow functionality the same and adds the timing logic your sector actually runs on. If your situation is genuinely standard, we’ll point you at a good SaaS option rather than sell you a build you don’t need.
Common Questions About Custom Cash Flow Management Tools
When is off-the-shelf cash flow software actually enough?
For a single entity with straightforward invoicing, standard payment terms and under roughly £50m turnover, tools like Float or Agicap usually do the job, and we'll tell you so. A custom build pays off when you have multiple legal entities to consolidate, industry-specific timing such as construction retention or subscription revenue recognition, conditional approval routing, or a proprietary forecasting model you don't want to hand to a generic tool.
How does the cost compare to a SaaS subscription?
A custom build is a larger one-off cost rather than a per-seat fee that climbs as your finance team grows. Most SME builds we scope land in the £15,000 to £50,000 range. Beyond the headline price, SaaS tools often carry setup fees, migration charges, premium-support surcharges and currency exposure when priced in USD or EUR. We don't promise a fixed payback date, but for a finance team of five-plus the per-user maths usually shifts in favour of owning the software.
What's the typical development timeline?
Most projects run 3 to 6 months: 2 to 4 weeks of discovery, 8 to 12 weeks of build, then testing and a phased go-live. A focused MVP, such as a 13-week rolling forecast with two or three bank feeds, can land sooner. Multi-entity consolidation and deep ERP integration take longer, and we give you a timeline after requirements analysis rather than before.
Can you integrate with our accounting software and bank feeds?
Yes. We connect to Xero, QuickBooks Online, Sage and FreeAgent, pull bank transactions via Open Banking, and link to ERPs such as NetSuite, SAP and Microsoft Dynamics. We handle the practical issues most teams hit: 24 to 48 hour bank feed lag, transaction deduplication between bank and ledger, and GL mapping for non-standard cost categories.
What about MTD, data security and compliance?
Every build handles VAT categorisation and MTD-ready reporting, with VAT liabilities shown in the forecast so a payment date never surprises you. We encrypt data in transit and at rest, log an immutable audit trail of who changed what, and can host entirely in the UK where data residency matters. Where you need SOC 2 or ISO 27001 alignment, we build to support it.
How do you handle updates, support and training?
Builds include 12 months of support and updates. After that you can take a support package or have us train your IT team to maintain the system. We train each user role to its needs: finance staff in detail, CFOs and department heads on the dashboards and reports, and your integration owner on the connectors.
