Reviewing contracts by hand eats senior time, and the software meant to fix it often just moves the problem. At ByteGears we build contract review automation tools for UK businesses from scratch. Off-the-shelf platforms make you bend your process to suit them. We do it the other way round.
We’re a London-based business automation consultancy. We build contract review tools that match how your legal, procurement and sales teams actually work, so the result cuts manual effort and keeps you on the right side of UK data and sector rules.
Where off-the-shelf contract review software falls short
Generic contract management and AI review platforms are capable products, and for some companies they’re the right call. But the same complaints come up again and again from UK buyers:
- Per-seat pricing that punishes rollout. Pricing is fine when only the legal team uses the tool. The moment procurement, sales and HR need access, the annual cost climbs hard. Cost is the single most common reason these projects stall.
- Workflows you have to fit, not the other way round. Most platforms assume a tidy approval chain. If your sign-off depends on contract value, counterparty, jurisdiction or whether a vendor is pre-approved, you end up working around the tool.
- Contracts uploaded to third-party AI. Several leading tools route documents through public AI services. For financial services, healthcare and other regulated firms, that’s a non-starter on data residency and confidentiality grounds.
- Patchy integration with what you already run. Slack, Teams and Microsoft 365 are usually covered. Legacy on-premise contract stores, custom ERPs and proprietary databases often aren’t, so contract data stays siloed.
- Long implementations that delay any return. Enterprise CLM rollouts of three to six months are common, and setup costs can run into five or six figures before anyone reviews a contract.
- Reporting that doesn’t answer the real questions. Dashboards look busy but can’t always tell you which renewals are coming, what you owe and when, or where spend sits by vendor.
The result is a pile of workarounds, contracts still being reviewed in parallel by email, and a team that quietly treats the tool as optional. Whatever you saved on the licence tends to evaporate.
When SaaS is genuinely the right answer
We’ll say this plainly, because not every business needs a custom build. If your contracts follow standard shapes (NDAs, MSAs, vendor agreements, employment letters), your volumes are modest, cloud storage is acceptable, and your approval process is a simple chain, an off-the-shelf platform is probably the sensible, faster choice. We’d rather tell you that than sell you a project you don’t need.
Custom tends to win when the picture is more awkward: highly specific contract types, strict data residency or on-premise requirements, approval logic with real conditional branching, deep integration with legacy systems, high volumes where per-seat licensing gets painful, or a long-term wish to own the system rather than rent it.
What ByteGears builds instead
We’re a small shop, and that shows up in the work.
Built around your contracts and your process
We model the review workflow you already use rather than imposing a new one. If sign-off escalates when a contract passes a value threshold, crosses a border, or names a counterparty that isn’t pre-approved, that logic lives in the system.
Playbooks tuned to your risk appetite
Clause checks are written against rules that match how your business actually treats risk, for example flagging liability caps below a set figure or a missing data processing clause. Tight playbooks mean fewer false positives, which is what keeps a team trusting the tool past month three.
Your data stays where it should
We can run clause extraction and analysis on your own infrastructure or in a UK or EU private cloud, so contracts never reach a public AI service. That makes GDPR and Data Protection Act 2018 obligations straightforward to evidence.
Pay once, own it
No subscription that never ends and no per-seat ceiling. You own the software outright and can give every relevant team access without watching the cost meter.
Fits the systems you already have
The build connects to Microsoft 365, Word, Slack or Teams, e-signature and document storage, and to your CRM or ERP. Where a legacy on-premise system is involved, we scope the integration work honestly instead of pretending it’s a switch you flip.
Support in your timezone
Our London team answers during UK business hours. No waiting overnight for a reply from another continent.
What the software actually does
Underneath, the system manages a clear set of records: contracts, the parties to them, the clauses inside them, the obligations they create, version history, amendments and the approval trail. A typical build includes:
- Clause detection and risk flagging — extracts liability, indemnity, confidentiality, IP and GDPR terms and scores them against your playbook
- Obligation tracking — pulls out deliverables, milestones, payment terms and renewal dates, with reminders before deadlines
- Approval workflows — serial, parallel or conditional routing that mirrors your real sign-off, including value-based and absence-aware escalation
- Version control and audit trail — every redline, approval and revision logged, with a clear record of which version is current
- Template and clause library — approved standard language your team can reuse
- Portfolio dashboard — contracts by status, value and risk, plus an obligation calendar and upcoming renewals
- Full-text search — find contracts by type, party, date range or clause content
- Role-based access control — permissions by role and department, so confidential contracts aren’t exposed to non-legal users elsewhere
- Document retention — auto-archiving aligned to your retention policy
- Integration layer — sync with CRM, ERP, e-signature and document storage so contract data isn’t stranded
We don’t pretend AI removes the lawyer. Clause detection is a strong first-pass reviewer that surfaces risk for a human to confirm. It is not a substitute for sign-off, and we build it that way deliberately.
How we build it
We ship a working system early rather than disappearing for six months.
1. Discovery and planning (2 to 4 weeks)
We walk through your current review process, the contract types that cause the most pain, your data residency rules and what needs to connect to what. We also audit the state of your existing contract data, because messy legacy contracts are the most common cause of slipped timelines.
2. MVP build (8 to 12 weeks)
We focus the first release on one or two high-volume contract types, a handful of core playbook rules, a simple approval workflow, the dashboard and Slack or Teams notifications. You get something usable while the rest is built.
3. Phase two (4 to 8 weeks, when needed)
More contract types, advanced and conditional playbooks, complex approval routing, CRM or ERP sync and richer reporting.
4. Testing, migration and rollout
We test hard, migrate your existing contracts in phases (recent first, older portfolio backfilled) and run alongside your current process before cutover, so nothing depends on a single risky switchover.
5. Training and support (ongoing)
Legal staff need a few hours; occasional users such as procurement or sales need far less. UK-based support continues afterwards.
Start to finish, a fuller build usually runs 18 to 26 weeks. We’d rather give you a real range after discovery than a confident number we can’t stand behind.
What it costs
A custom build costs more upfront than a SaaS subscription. Here’s the honest trade-off.
- A fixed build cost and a modest annual maintenance figure — no per-seat licence, no annual price rises
- Full ownership — your software, your data, no vendor lock-in and no painful migration if you outgrow a supplier
- Cost that scales with the business, not with headcount — adding users doesn’t add licence fees
- Capital expenditure rather than an operating cost — worth a conversation with your accountant
Watch the hidden costs on the SaaS side too: data migration, integration services, training, premium support tiers and storage overage charges rarely sit in the headline price. For organisations rolling a tool out widely, or reviewing high contract volumes, three-to-five-year ownership of a custom system often comes out lower. We won’t put a guaranteed payback figure in writing, because it depends entirely on your volumes and how many people use it. The free consultation is where we work that out with you.
Industries we build this for
The data model and workflows change a lot by sector, so we adapt the build rather than reskinning a template.
- Financial services — counterparty and facility agreements, FCA reporting obligations, internal credit policy embedded in playbooks where generic models miss esoteric terms
- Professional services and law firms — client engagement terms, NDAs and precedent management tied to your own methodology
- Property and construction — leases, subcontractor agreements and change orders, with obligations tied to specific buildings, tenants and date ranges
- Healthcare and biotech — provider and supplier agreements, patient-data handling, CQC-aligned checks and complex IP, royalty and milestone structures
- Manufacturing and supply chain — supplier agreements and SLAs with tiered-vendor approval routing and spend roll-up
- Technology and SaaS — customer MSAs, DPAs and non-standard commercial terms such as usage-based or marketplace pricing, with tight CRM integration
- Charities and the public sector — grant agreements and procurement contracts, Charity Commission or Ofsted requirements, FOI-ready audit trails and standstill rules
Whatever we build, we shape it around how your sector actually works rather than the other way round.
Common Questions About Custom Contract Review Automation Tools
How does a custom build compare on cost to a SaaS contract review platform?
The numbers turn on how many people need access. Per-seat platforms are sensible when only a small legal team uses them, but the cost climbs sharply once procurement, sales and HR need logins too. A custom build has a larger upfront cost and a modest annual maintenance figure after that, with no per-user licence. For organisations rolling out to 20-plus users, or reviewing four-figure contract volumes a year, ownership over three to five years usually works out lower. We give you a proper comparison against your actual usage before you commit.
What's a realistic timeline?
A working MVP covering one or two high-volume contract types, basic playbook checks, a simple approval workflow and Slack or Teams notifications is typically 8 to 12 weeks. A fuller build with advanced playbooks, CRM or ERP sync, complex approval routing and portfolio reporting usually runs to 18 to 26 weeks. We deliberately ship the MVP first so you get value while the rest is built.
Do contracts have to leave our network or go to a third-party AI service?
Not unless you want them to. Many regulated firms can't upload contracts to public AI services, so we can run the clause-extraction and analysis models on your own infrastructure or in a UK or EU private cloud. Nothing leaves your environment. This makes GDPR and Data Protection Act 2018 obligations far easier to evidence in an audit.
Can it connect to our existing systems?
Yes. Common connections include Microsoft 365 and Word, Slack or Teams, e-signature tools such as DocuSign or Adobe Sign, document stores like SharePoint or Box, and CRM or ERP systems such as Salesforce, HubSpot or NetSuite. Legacy on-premise databases that lack modern APIs need custom integration work, and we scope that honestly rather than pretending it's a plug-in.
How accurate is the clause detection, and can we trust it?
AI clause extraction is good at pattern-based work but not infallible, and accuracy drops on long or unusual agreements. We treat it as a first-pass reviewer that flags risks for a human to confirm, never as a replacement for legal sign-off. Playbook rules are written against your own risk appetite so you don't drown in false positives, which is the most common reason teams quietly stop trusting these tools.
What about GDPR and sector compliance?
The system is built around UK GDPR and the Data Protection Act 2018, with role-based access, document retention rules and a full audit trail of every redline, approval and version. Playbook checks can flag missing data processing clauses, weak liability caps or absent breach-notification terms. Where you operate under FCA, CQC, HSE or Charity Commission rules, we embed the relevant checks into the review workflow rather than leaving you to configure a generic compliance log.
