What slows online sellers down, and how Tryso fixes it
Businesses selling mainly through their own website, with deliveries by courier.
The problem
A website that does not know the stock
Products stay on sale online after they have sold out.
With Tryso
The storefront sells from your real stock and reserves it as orders come in.
The problem
Courier paperwork
Waybills and tracking numbers are copied by hand.
With Tryso
Supported couriers generate waybills and sync tracking back to the order.
The problem
Disconnected payments
Card, transfer and cash on delivery are reconciled manually.
With Tryso
Orders carry their payment method, and paid orders post to the books.
How it works
How online sellers run on Tryso
From the first delivery to the end of the day, each step happens in the app built for it, on one shared database.
- 1
Publish
Products go live on your own storefront and domain.
Website & online store - 2
Take orders
Orders reserve stock and take payment.
Sales - 3
Ship

Shipping - 4
Account
Sales post to the books as orders are paid.
Accounting
One count for every shelf, store room and branch
Each branch and warehouse holds its own quantity, and the business total is simply their sum. Transfers between locations are documents with a sender and a receiver, so stock never disappears in transit and nobody has to phone round to find a product.
- Quantity per branch and per warehouse
- Transfers that both sides confirm
- Reservations for orders not yet shipped
Batches and expiry dates on every delivery
Receive goods with a batch number and expiry date, and see which batch is oldest before you pick. Food, medicine and cosmetics leave the shelf in date order instead of being found after they have expired.
- Batch and expiry captured at goods receipt
- Oldest stock visible when picking
- Low stock thresholds per product and variant
Every change has a reason and a document
Counts, damages and write-offs are adjustments with a reason on every line, and sales, receipts and transfers are movements against the same ledger. When a number looks wrong, you can trace it to the document that changed it.
- Adjustments with a reason per line
- Receipts that move stock and valuation together
- Stock valuation from recorded movements

Frequently asked questions
Does Tryso connect to couriers?
Yes. Courier providers are configured per organization, and supported couriers generate waybills and sync tracking back to the order.
Can I bring my products from Shopify or WooCommerce?
Yes. The migration tool imports products and customers from Shopify, WooCommerce or a custom API.
What is inventory management software?
Inventory management software records every stock movement, such as sales, purchases, transfers and adjustments, so you always know how much of each product you have and where it is. Tryso keeps one stock ledger for the shop floor, the online store and the warehouse.
Can Tryso track stock across several branches?
Yes. Stock is held per branch and per warehouse, and transfers between them are recorded documents, so each location shows its own quantity and the business total adds up.
Does Tryso support batch and expiry tracking?
Yes. Products can be received in batches with expiry dates, which matters for pharmacies, food and cosmetics where you need to sell the oldest stock first.
Will online orders reduce my stock automatically?
Yes. Orders from your Tryso storefront reserve stock when they are placed, so you cannot sell the same item twice across the website and the counter.
Is there a free inventory plan?
Yes. Tryso has a free plan with no card required, so you can load your products and try stock tracking before you pay for anything.
