Accounting integrations
Invoices, customers and payments that pass back and forth between your web shop or quoting tool and your accounting package.

Enter data once and have it appear where it is needed: that leaves you time for your own work.
01What you get
In many businesses the same data is typed in three places: in the web shop, in the accounting package and in an Excel list. That costs time and causes errors. Assist2go connects your systems and automates whatever can be repeated.
Invoices, customers and payments that pass back and forth between your web shop or quoting tool and your accounting package.
Orders, stock and shipping status in line, so you do not sell what you do not have.
A request through the website arrives as a contact and a job in your CRM, and an approved quote becomes an invoice.
A task that is always the same happens by itself, and you get a message if something fails.
Figures from different systems brought together automatically, without copying them by hand every month.
Confirmations, reminders and invoices that are sent or saved at the right moment.
02In depth
Almost every package you use daily has a way to exchange data, usually through an API or a standard integration. Common combinations in small businesses are: a web shop that passes orders to the accounting package, a quoting tool that turns an approved quote into a job and an invoice, a calendar that sends a confirmation when an appointment is made, and a form on the website that lands in your CRM.
Whether an integration is worth it depends on how often something happens and what a mistake costs. An integration for three invoices a month is better left manual. An integration for forty orders a day pays for itself quickly, and prevents the typing errors that come with manual work.
03
There are three ways to connect systems. Many packages have a standard integration with another package, often as a module: that is the first choice, because it is the easiest to maintain. For simple rules there are tools such as Power Automate, which lets you build a flow without code. For complex rules, large volumes or unusual packages we build a custom integration.
We start with the simplest solution that works and only build ourselves what cannot be done otherwise. That keeps costs low and management clear. If an integration is part of a larger custom project, you can read more under custom software, ERP and CRM.
04
Most of the gain is in work that repeats often, follows fixed rules and produces errors when done by hand: sending reminders for unpaid invoices, creating accounts when someone starts, preparing a report every Monday, saving attachments in the right place. These are small jobs that together cost a day a week.
Where documents or email need to be read or pre-sorted, AI can help. We use it where it is reliable and keep a person involved in decisions where a mistake would do damage.
05
An integration has access to your data and so must be treated as carefully as a member of staff. We use separate access keys with as few permissions as possible, store them securely and record what has been connected. If an integration fails, you or we get an alert, so no data goes missing without anyone knowing.
How we work
Which systems do you have, where do you enter things twice and what does that cost? We start with what pays off most.
We build the integration, test it with real data and only put it live once the results are right.
We keep an eye on the integration, adjust it when a package changes and report faults before you notice them.
