Systems we integrate with every week
Real products with real constraints: multi-tenant data, role-based permissions, subscription billing, legacy system integration and audit trails. Explore the architecture behind each build.
Course delivery, community and subscription billing lived in three separate subscriptions. We consolidated them into one custom membership site with tiered access, Stripe billing, drip-released content and an admin console for the editorial team.

Uptime
Adam Hayes
Head of Product, Meridian
Account managers were emailing spreadsheets of shipment data. We built a secure portal where enterprise clients log in with SSO to track consignments, raise collections and download invoices, synced live from their NetSuite instance.

Audit Coverage
Rachel Grant
COO, Northwind Logistics
Tessellate needed one platform serving hundreds of independent venues, each with their own branding, staff roles and pricing. We built tenant-isolated workspaces on a shared schema with Stripe Connect split payouts and calendar sync.

Jonah Blake
Founder, Tessellate
A 60-person claims team ran their entire pipeline through spreadsheets. We built a workflow application with document intake, rules-based routing, SLA timers and an immutable audit trail that satisfies their regulator.

Audit Trail
Nadia Mirza
Ops Director, Verity Claims
Orders, inventory and accounting data drifted between Shopify, a 3PL, an ERP and four sales channels. We built a middleware service with webhook ingestion, idempotent job processing and a reconciliation dashboard that flags mismatches automatically.

Weekly Reconcile
Tomas Oliveira
CTO, Loop Commerce
Engineers work in basements and rural sites with no signal. We built an installable, offline-first web app with local-first storage, conflict resolution and background sync so job sheets capture perfectly and upload when connectivity returns.

Cold Start
Sofia Marchetti
Field Ops Lead, Atlas
Integrations are where most custom software projects quietly fail. We treat them as first-class architecture: versioned contracts, retry queues, idempotency keys, reconciliation reports and audit logs on every payload.
Recurring subscriptions, usage billing, marketplace splits, dunning and revenue reporting.
Single sign-on, multi-factor authentication, role hierarchies and invitation flows.
Lead capture, pipeline sync and two-way contact and deal synchronisation.
Invoice sync, inventory and order flows, reconciliation and tax-ready exports.
Transactional email, SMS alerts, in-app notifications and delivery webhooks.
Event pipelines, warehouse sync and product dashboards your team will actually read.
Webhook pipelines, scheduled jobs, iPaaS flows and documented public REST/GraphQL APIs.
Headless storefronts, product and order sync, fulfilment handoff and returns logic.
Whether it is a membership site, an internal tool or a full SaaS product, the same hardened foundations are included by default — not sold back to you as add-ons later.
Tiered plans, proration, trials, coupons, failed-payment retries and cancellation flows handled end to end.
Granular role matrices, tenant isolation and permission checks enforced server-side on every request.
Membership tiers, scheduled content unlocks, progress tracking and gated downloads or video.
REST, GraphQL and webhook integrations with retries, idempotency keys and reconciliation dashboards.
MRR, churn cohorts, activation funnels and member engagement reporting built into your admin panel.
Encrypted secrets, audited authentication, rate limiting, automated backups and data export or deletion workflows.
No black-box development. You see working software every week, in a staging environment you can click through, with a fixed scope agreed before the first sprint starts.
Workshops, user flows, data modelling, integration mapping, security requirements and a fixed-scope sprint plan.
Information architecture, UI design system and a clickable prototype so you can react to real screens before code.
Two-week build sprints with demo calls, automated tests, connected integrations and a staging URL from day one.
Cross-device QA, performance and security passes, data migration, launch, then code and infrastructure handover.
Every engagement is delivered in fixed-price milestones with written acceptance criteria. Repositories, database schema, infrastructure accounts and documentation are transferred to your name at launch — and if a milestone does not meet its agreed criteria, we fix it before we invoice for the next one.

"We replaced three SaaS subscriptions with one custom membership platform and cut churn by 38%. The Dotted Tech understood our billing edge cases better than the tools we were paying for."
Adam Hayes
Head of Product, Meridian Learning
"Our ERP integration had failed twice with other agencies. These guys shipped it with retry queues and a reconciliation dashboard, and we have not had a single data mismatch since."
Rachel Grant
COO, Northwind Logistics
"Fixed price, weekly demos and clean handover documentation. We took the codebase in-house after launch with zero drama, which is exactly what we wanted."
Jonah Blake
Founder, Tessellate Booking
Everything founders and product teams ask us before booking a strategy call.
Have a specific technical constraint, legacy system or compliance requirement?
Bring us the messy version — the process living in spreadsheets, the membership site you have outgrown, the integration that keeps breaking. The Dotted Tech will tell you what it takes to build it properly.
