TailorStack replaces the bloated SaaS your team works around — CPQ, billing, forecasting, CLM — with software cut to fit your exact business. Shipped in weeks. Fixed price. You own it forever.
Most revenue teams are drowning in SaaS that half-works. 15 years at Salesforce, Thomson Reuters, and Medallia showed us exactly where these tools break. We replace them with one tailored system that actually fits.
Configure-price-quote with multi-currency pricing matrices, tiered approval chains, and PDF contract generation. Built around your actual catalogue — not forced into someone else's object model.
Subscription management with automated invoicing, credit notes, payment reconciliation, and audit logging. Purpose-built for your revenue model — usage-based, tiered, hybrid. No platform tax.
CRM-integrated forecasting with AI-adjusted predictions, deal qualification scoring, manager overrides, and goal tracking per team and rep. A system you understand, control, and actually trust.
Contract lifecycle management with AI-powered document extraction, OCR scanning, clause tagging, and automated approval routing. Your legal workflows drive the system — not the other way around.
Custom AI software — RAG pipelines, vector databases, document extraction (OCR), and AI agents. Production-grade applications built around your actual business data, not generic wrappers.
Not in revenue? Doesn't matter.
We've shipped a consumer finance app with Stripe payments, AI chat, and multi-language support — alongside every revenue tool above. Internal dashboards, client portals, workflow automation, data pipelines — if it's off-the-rack software that doesn't fit, we'll tailor the version that does.

TailorStack builds the alternative — one system, measured to your exact requirements. Built in weeks. Production-grade. Yours forever.
We map your current stack — what you're paying, what you're actually using, where the waste is.
Fixed-price scope. Clear timeline. No ambiguity — you know exactly what gets built and when.
Custom software, tailored to your workflows. AI-native where it counts. You own the code, the data, everything.
Deployed, documented, team trained. Cancel your old licenses. Ongoing support if you want it.
15+ years leading revenue operations at Salesforce, Thomson Reuters, Medallia, and TransferRoom — Series A to Fortune 500. I was the person buying, implementing, and eventually ripping out the SaaS tools that didn't fit. I know what broken looks like from the inside.
Most companies don't have a software problem. They have a systems problem — fragmented tools, manual workarounds, disconnected processes duct-taped together. The result is the same everywhere: three tools doing one job, none of them doing it well, and a team spending half its time bridging the gaps.
TailorStack exists to fix that. I take your broken processes, disconnected cadences, and half-fitting SaaS — and I build one cohesive engine, custom-designed around exactly how your business works. AI makes it possible to build production-grade software in weeks instead of months. Document extraction, pipeline predictions, anomaly detection — baked in where it adds real value, not as a wrapper.
A custom build typically costs a fraction of one year's SaaS licensing — and it's a one-time fixed price. Most clients replace £60k–100k+ in annual SaaS spend. When you factor in implementation consultants, ongoing maintenance, and productivity lost to workarounds, most SaaS tools cost 3–5x their sticker price. A tailored build eliminates all of those layers.
Most builds ship in 4–8 weeks from scoping to deployment. CPQ and forecasting systems typically land in 4–6 weeks, while more complex builds like CLM platforms with AI document extraction take 5–7 weeks.
You get a deployed system with full documentation and team training. Ongoing support is available if you want it — but you're never locked in. Any developer can maintain or extend the codebase. When your business evolves, you update the software directly instead of filing a support ticket.
Yes, completely. Source code, data, infrastructure — it's all yours. No vendor lock-in, no licensing fees, no renewal conversations. You can hire any developer to maintain or extend it.
The initial scope is fixed-price with a clear spec. If new requirements emerge, we scope them as a separate phase with its own fixed price. No billable-hour surprises, no scope creep anxiety.
No. Every build comes with documentation, training, and a codebase that any competent developer can pick up. Most clients run their systems without ongoing technical support. If you do need changes, we're available for follow-up work.
Yes. Revenue ops is our home turf — 15 years of domain expertise. But we've also shipped a consumer finance SaaS with Stripe payments, AI chat, and multi-language support. Internal dashboards, client portals, workflow automation — if it's off-the-rack software that doesn't fit, we'll tailor the replacement.
We'll audit your current stack, estimate your savings, and show you exactly what we'd build. No commitment, no pitch deck. Just a clear picture of what's possible.
