We connect your system to e-invoicing, payments, and your existing tools

Choose JoFotara and payments integrations when your current system is sound and you need a reliable tax or payment layer. Do not replace a working platform — add a clear path for invoices and collection. If you are building a new product from scratch, fold integrations into the SaaS project instead of a separate engagement.

BarmajTek integrations focus on national e-invoicing and payment paths that disrupt operations when they fail. We document retries, logs, and responsibility boundaries so the connection is not “magic” to accounting. Clinic Tek demonstrates electronic invoicing ready for national paths inside a product used by real clinics, and the clinics solution shows where the invoice belongs in the clinic day. The case study adds tenant isolation, backups, and data export context. Before kickoff, ask to see a signature failure or gateway decline and how retries avoid duplicate manual entry. Record who owns environment keys, who reviews logs, and who corrects a rejected invoice. If the current platform is sound, we add an adapter layer around it; if you are building new SaaS, we design those boundaries into the architecture. Scope starts with a written data contract for every event: identifier, amount, currency, state, timestamp, and which system owns truth when records disagree. Idempotency prevents duplicates, webhook signatures verify origin, and queues retry within declared limits. We test timeouts, duplicate notifications, out-of-order events, provider outages, and daily reconciliation between internal and external records. Secrets and sensitive fields stay out of logs while enough evidence remains for investigation. Integration failure then becomes a managed state rather than a surprise that stops invoicing.
