Keep ERPNext for stock, buying and accounts. Tidal does the typing that happens before it: RFQs become priced quotes, supplier invoices become checked bills, and both land in ERPNext once a person approves.
No change to your ERPNext set up. Connected through its API or an import file.
The short answer: yes, Tidal works with ERPNext. ERPNext (built on the Frappe framework) is an open source ERP that many ship chandlers and marine suppliers run for stock, buying, selling and accounts. Tidal sits in front of it: it reads RFQs and supplier invoices, prices and checks every line, and after a person approves, creates the Sales Order or Purchase Invoice in ERPNext with your own item, customer, supplier and tax codes. Works the same way on Frappe Cloud and on a self hosted ERPNext.
Two documents, each with the codes ERPNext already uses.
| In Tidal | In ERPNext | When |
|---|---|---|
| Approved quote | Sales Order | When your customer accepts the quote |
| Approved supplier invoice | Purchase Invoice | When a person approves it on the review screen |
| Catalogue product | Matched to the Item code | Loaded once from your item list, then kept current |
| Customer and supplier | Matched to the Customer and Supplier | Mapped once during set up |
Pick the one your team and your IT partner are comfortable with. You can start with files and move to the API later.
Tidal connects through ERPNext’s REST API, which creates documents such as Sales Order and Purchase Invoice directly.
Tidal produces a CSV or Excel file laid out for ERPNext’s Data Import tool.
Each module is sold on its own.

RFQs read in any buyer layout, every line priced from your catalogue and supplier prices, and the approved quote sent to ERPNext as a Sales Order.

Supplier invoices sent as a photo or PDF are read line by line, checked, approved by a person and created in ERPNext as a Purchase Invoice.
