e-conomic integration that just works.

Automatic invoicing, two-way sync, robust error handling. Built on e-conomic's official API with concrete experience from Waitly's billing flow, where each individual association had its invoice calculated, generated, and dispatched automatically every month.

01 / what it is

What an e-conomic integration solves.

For SMBs & SaaS platforms

An e-conomic integration connects your business system directly to your accounting. Customers, products, orders, invoices, and payments sync automatically, in the direction and cadence that fits your workflow.

It's typically relevant when you have a webshop, a SaaS platform, an inventory system, or a CRM where data otherwise has to be moved manually between systems. The result is that accounting data is always up to date, billing runs in the background, and you spend time on the actual work instead of data entry.

The integration is built robust with retry logic, idempotent operations, and logging, so you can see precisely where something might go wrong, not just that it did.

02 / scenarios

Typical work.

What I often build
02.A, billing

Automatic monthly invoicing

Your SaaS or service business calculates an amount per customer per period. I build the logic and let e-conomic generate and send the invoices.

02.B, webshop

Webshop → e-conomic

Orders, customers, and invoices from WooCommerce, Shopify, Magento, or your custom webshop sync directly into e-conomic.

02.C, inventory & products

Two-way product/inventory sync

Products, variants, stock levels, and prices stay synchronized between e-conomic and your other systems. Change one, both update.

02.D, payments

Payment reconciliation

Incoming payments from Stripe, MobilePay, or bank transfers are automatically matched with open invoices in e-conomic.

02.E, customer data

CRM customer sync

Customers and contacts kept up to date between your CRM (HubSpot, Pipedrive, Salesforce, or custom) and e-conomic, with one source of truth as master.

02.F, reporting

Accounting export / reporting

Pull data out of e-conomic into dashboards, BI systems, or custom reports with your own logic on top.

03 / approach

How I build it.

Robust & observable
API
Built on e-conomic's official REST API + webhooks, so the integration stays in sync as e-conomic evolves.
Architecture
Job queue-based (Laravel Horizon or equivalent). Jobs are idempotent, the same operation can run twice without duplicating data.
Error handling
Retry with exponential backoff, dead-letter queue for jobs that ultimately fail. Each error logged with context, making it possible to diagnose and retry.
Observability
Structured logging + alerting on abnormal error rates. You know when something breaks, and where.
Security
Credentials in secrets manager, OAuth where possible, rate-limit awareness. Follows e-conomic best practices for production integrations.
Maintenance
Documentation as part of delivery. You can take over operations yourselves, or I can handle ongoing maintenance as agreed.
04 / FAQ

Frequently asked.

Short answers

Can you integrate e-conomic with our webshop / CRM / inventory?

Yes. I build two-way synchronization between e-conomic and your other systems, customers, products, orders, invoices, and payments flow automatically via REST and webhooks.

Do you build automatic invoices based on data from our system?

Yes. At Waitly I built a complete billing system where each association had its invoice calculated based on activity, the invoice was then automatically generated and dispatched via e-conomic. The same approach can be adapted to your business logic.

What happens if e-conomic is down or an API call fails?

The integration is built with retry logic, idempotent operations, and dead-letter handling. Each task is logged so you can see exactly where something went wrong, and automatically retry once e-conomic is back.

What does an e-conomic integration cost?

Hourly rate is DKK 950/hr (~$130 USD) ex. VAT. Smaller integrations (a single sync or invoicing flow) typically range from 15–40 hours. Larger multi-system integrations are agreed as fixed price after initial scoping.

Do you use e-conomic's official API?

Yes. The integration is built on e-conomic's official REST API and webhooks, so it stays in sync as e-conomic evolves.

Can you take over an existing e-conomic integration?

Yes. I can take over an existing integration, assess what can be built on, and deliver both updates and documentation so you have full visibility into the solution going forward.
