B2B software development for the procurement team who asks for SSO.

B2B software development for UK and EU founders selling into enterprise. A generic SaaS stalls in procurement. We build the multi-tenant spine with SSO + SAML + SCIM, per-tenant audit log, a role and permission engine, and the SOC 2 evidence pipeline your buyer’s security team walks through without flinching.

(Why B2B founders sign)

You build for the user. We build B2B software for the buyer’s security team, the auditor, and the user, all at once.

Your enterprise pilot won’t die in procurement again. Enterprise SaaS development means SSO, SCIM, audit trails, and a security pack are designed in at architecture, not bolted on the week the security questionnaire lands.

The founder this page is for£1.4M ARR · pilot stalled six months · signed

Anya sold the demo. The product won the room. Procurement quietly killed it.

01

Anya founded a UK B2B revenue-ops platform and grew it to £1.4M ARR on product-led growth. Then an enterprise pilot reached the security team. They asked for SSO. No SAML. They asked for an audit log. She had server logs. They asked for SCIM provisioning and a SOC 2 report. Nothing, and nothing. Six months of pilot died in procurement.

02

The product wasn’t the problem. The B2B software spine was. She’d treated enterprise readiness as a thing the next round would fund. By the time the buyer’s security questionnaire landed, every gap was a fortnight of senior engineering she didn’t have.

03

We rebuilt the enterprise spine over fourteen weeks: WorkOS for SSO + SAML + SCIM, a per-tenant audit log, a SOC 2 Type 1 evidence pipeline in nine weeks via Vanta. The stalled pilot signed. Then two more in the same quarter. This page is for the B2B software founder who’d rather build with the auditor in mind on day one.

Enterprise-ready since 2019
The six things your buyer’s security team will ask about

Enterprise SaaS foundations.
Day one, not week ten.

Every B2B software build we’ve shipped since 2019 makes the same six load-bearing decisions on day one. Each one is hard to retrofit. Each one closes a question on the procurement security call. Open any row.

WorkOS, Auth0, or Okta. Per-tenant identity provider. Just-in-time provisioning on hire, deprovision on offboard. When procurement asks for SAML, it’s a config switch, not a one-month rebuild that loses the deal.

Row-level security or schema-per-tenant in Postgres. Every query carries the tenant ID. A misrouted query returns zero rows, not someone else’s customer data. Cross-tenant leak is architecturally impossible, not policy-prevented.

Who did what, when, from which IP. Tenant-admin viewable. Exportable to Splunk, Datadog, or Snowflake. The day an auditor says “that’s not an audit log, those are server logs”, you’re already past it.

Owner, admin, member, viewer, plus custom roles per tenant. Permission delegation and approval workflows. The access model your enterprise customer asks about in week one is the model you wrote on day one.

Vanta, Drata, or Secureframe wired from week one so the clock starts immediately. Continuous evidence collection. SOC 2 Type 1 achievable in 8-12 weeks, ISO 27001 in 16-26. SOC 2 stops being a six-month panic.

SIG-Lite or CAIQ filled. DPA template, sub-processor list, pen test, SLA. Tenant-pinned region for EU, UK, or US residency with Standard Contractual Clauses where data crosses borders. The vendor security review clears in days.

WHAT TURNS A DEMO INTO AN ENTERPRISE DEAL

Four things that move a B2B SaaS past the security gate

The engineering that separates a clever B2B tool from a platform a Fortune-500 procurement team is allowed to buy.

01

Identity that procurement accepts

SSO + SAML + SCIM via WorkOS or Auth0. Per-tenant IdP, just-in-time provisioning, deprovision on offboard. The first thing the security team checks, already done.

02

An audit log an auditor signs off

Per-tenant, immutable, IP-stamped, SIEM-exportable. Not application server logs renamed. The artefact that turns SOC 2 from a panic into paperwork.

03

Tenant isolation that’s provable

Postgres row-level security or schema-per-tenant. Tenant pin enforced at the database. A leak isn’t prevented by policy, it’s impossible by design.

04

A procurement pack on the shelf

SIG-Lite + CAIQ filled, pen test report, architecture diagram, DPA, SLA. The 60-page security questionnaire answers itself instead of stalling for a month.

The eight pains UK B2B software founders bring us

The B2B software pain. The day-1 answer.

Every B2B founder who emails us is fighting one of these eight things. Each one is impossible to fix cheaply once the codebase is live and an enterprise buyer is waiting. Each one is a single architectural decision made on day one of our build.

  1. 01
    No SSO = no enterpriseDay-1 architecture

    “Procurement asked for SAML. We had no answer. The pilot died.”

    WorkOS / Auth0 SAML + SCIM in two weeks. Per-tenant IdP, just-in-time provisioning. The procurement security gate clears instead of stalling the deal.

  2. 02
    Your audit log isn’t oneDay-1 architecture

    “We had server logs. The auditor said ‘that’s not an audit log’. Stalled.”

    Per-tenant immutable audit log. Who did what, when, from which IP. Tenant-admin viewable. SIEM export. The auditor is satisfied on the first pass.

  3. 03
    Cross-tenant leak riskDay-1 architecture

    “An engineer queried by user-ID without a tenant filter. Customer data leaked.”

    Tenant pin enforced at the data layer. Row-level security or schema-per-tenant. A cross-tenant query is architecturally impossible, not policy-prevented.

  4. 04
    No SOC 2 = procurement stallDay-1 architecture

    “Enterprise asked for SOC 2 Type 1. We had none. A six-month stall.”

    Vanta wired Day 1, SOC 2 Type 1 in 8-12 weeks. Continuous evidence collection. Type 1 achievable in 8-12 weeks, Type 2 in six months. The clock starts on day one.

  5. 05
    Data residency demandDay-1 architecture

    “An EU enterprise wanted EU residency. We were US-only and couldn’t move.”

    Tenant-pinned region (EU / UK / US). Tenant data pinned to region. Sub-processor list per region. Standard Contractual Clauses where data crosses a border.

  6. 06
    Security pack missingDay-1 architecture

    “Procurement wanted SIG-Lite. We didn’t know what that was.”

    SIG-Lite + CAIQ + pen test ready. Procurement pack on the shelf Day 1. Pen test report, architecture diagram, DPA, SLA. The security review clears in days.

  7. 07
    CSM has no admin toolsDay-1 architecture

    “Our CSM had to ask engineering for everything. Total bottleneck.”

    CSM console with safe impersonation. Audit-logged impersonation, bulk operations, usage analytics per tenant. The engineering bottleneck closes for good.

  8. 08
    Procurement billing failDay-1 architecture

    “Enterprise wanted PO + Net 60 + Coupa. Stripe-only didn’t fly.”

    Stripe + PO + invoice + procurement. Stripe for SMB, PO + invoice + Net 30/60/90 for enterprise. Coupa / Ariba onboarding. Multi-currency, VAT-aware. Procurement teams clear it.

B2B software development · honest answers

What B2B software founders actually ask before signing the contract

Pain-first, soft-second. The questions every founder asks once an enterprise buyer is waiting on the other side.

Realistically 8-12 weeks with Vanta or Drata for Type 1. Type 2 needs six months of observation. On every B2B software development build we wire the evidence pipeline on day one, so the clock starts immediately rather than the day someone panics about a questionnaire. We’ve shipped this nine weeks end to end when the brief was tight.

WorkOS for the fastest enterprise SAML + SCIM. Auth0 for a richer identity feature set. Stytch for embedded auth flexibility. We’ll match the pick to your stage and your buyer profile, and we’ll stub the SSO paths from day one so flipping it live is a config change, not a one-month rebuild that costs you the deal.

Tenant pin is enforced at the data layer, with PostgreSQL row-level security or schema-per-tenant. A cross-tenant query returns zero rows, not someone else’s customer data, so a leak is architecturally impossible rather than policy-prevented. We add a per-query tenant assertion in the ORM as a second belt, and the audit log records every read so you can prove it.

We don’t price by salesperson mood. The audit week is fixed at £8K. After that, every B2B software build is line-itemed into the scope: identity, multi-tenancy, audit log, role engine, admin + CSM console, procurement pack, billing. You see the cost of each piece and can cut any piece. Most enterprise SaaS builds we sign land between £65K and £120K on an 8-to-14-week fixed-price sprint. If we can’t hit your budget, we tell you in week one and you keep the audit brief.

Yes, tenant-pinned region. EU on AWS Frankfurt or Dublin, UK on London, US on us-east-1 or us-west-2. Sub-processor list per region. Standard Contractual Clauses where data crosses borders. The residency story is designed into the data layer on day one, so adding an EU buyer later doesn’t mean re-architecting the whole platform.

Three things make this hard to fake. First, the 30-day walk-away clause goes both ways and refunds the unused portion. Second, payments are milestoned 25/25/25/25, so you never pay more than 25% ahead of working software. Third, we’ve been shipping since 2019 with 200+ projects under our name, listed on Companies House, UK VAT registered. Check us before you sign.

This is the biggest risk with a small studio, and the reason we run our process the way we do. Every project pairs two senior engineers, not one. Every decision is written into an ADR the same day. Every commit goes through Mohit’s review. If one engineer leaves, the other has full context the next morning. In seven years, two engineers left mid-project. Both handovers were inside 48 hours. Neither client noticed in their sprint.

Yes, with 14 days’ notice. The engineers move to other projects, your repo stays where it is, your spend pauses. Pick it back up with 14 days’ notice and we resume on the same sprint board with the same engineers. No cancellation fee, no restart fee. We’ve done this six times in 2025, and two clients paused for four months. Both came back, both shipped.

Yes, signed inside 30 minutes via DocuSign. We keep a mutual NDA template ready so it never becomes the thing that delays the first real conversation. Your B2B software idea, your customer list, and your roadmap stay yours.
