How US small & mid-size businesses use this service

The Bottleneck

Bookkeepers manually re-typing HubSpot/Salesforce deals or Shopify custom orders into QuickBooks with frequent sync errors.

What We Build

Business Outcome

100% accurate real-time accounting sync and 10–20 hours of manual bookkeeping saved every week.

The Bottleneck

Zapier or Make tasks failing silently or costing hundreds of dollars a month on high-volume webhook events.

What We Build

Dedicated Node.js/Python API middleware hosted on your own cloud with full logging, rate-limit handling, and zero per-task fees.

Business Outcome

Enterprise-grade reliability at a fraction of ongoing no-code middleware costs.

Common questions about Integrations & APIs

How much does a custom QuickBooks, Stripe, or CRM integration cost?

Most custom point-to-point or multi-system API integrations are estimated between $3,500 and $9,500 (20–25% below standard US integration consultancies) and ship in 2–4 weeks. Prices are estimates and are adjusted based on the number of endpoints, data volume, and business logic complexity.

Why build a custom API integration instead of just using Zapier?

Zapier is great for simple triggers, but it struggles with complex conditional logic, multi-line QuickBooks invoices, historical backfills, high event volume, and strict error recovery. A custom integration handles your exact edge cases with automatic retries and zero per-task markups.

How do you prevent duplicate records or missed webhooks?

We engineer every integration with idempotency keys, dead-letter retry queues, audit logs, and automated Slack/email alerts so no invoice, order, or customer record is ever duplicated or dropped.
