Purchase Order Software
That Raises Itself
Replenagise is purchase order software for ecommerce. It forecasts demand on every SKU, converts the forecast into a suggested PO per supplier, and raises it straight into Shopify or Linnworks — one click, or fully automated.
The purchase order should be the output, not the work
Most purchase order software starts where the hard part ends: you still have to work out what to order, how much, and when — then key it in. Replenagise flips that. The demand forecast on every SKU flows into reorder points, safety stock, and cover periods, and comes out the other side as a ready-to-send purchase order with quantities already calculated.
Review it, adjust it if you want, and raise it into Shopify or Linnworks with one click. Or set the automation live and let routine POs run themselves — you approve exceptions instead of typing spreadsheets.
Everything PO Software Should Do
Auto-Calculated Order Quantities
Order quantities are computed from stockout-adjusted sales velocity, supplier lead times, cover periods, and safety stock — recalculated as demand shifts, so every PO reflects what is actually selling.
One-Click & Fully Automated POs
Raise a suggested purchase order into Shopify or Linnworks in one click, or automate the whole loop so POs are created on schedule when SKUs hit their reorder points.
Supplier Management & Lead Times
Suppliers, cost prices, currencies, and lead times live in one place. POs are built per supplier with the right costs attached, and lead times feed straight back into the reorder math.
Multi-Currency & Multi-Location
Order in your supplier’s currency, plan per warehouse and location, and pair purchase orders with stock transfers so new stock lands where demand actually is.
Built for Shopify & Linnworks purchasing teams
Generic PO tools stop at a PDF. Replenagise raises real purchase orders inside the platforms that run your operation — Shopify and Linnworks — so received stock, costs, and supplier records stay in sync without re-keying.
And because the same engine does the forecasting, your buying decisions and your paperwork can never drift apart: the quantity on the PO is the quantity the demand model asked for.
Purchasing is one half of the loop — see how it connects to inventory replenishment software, learn the maths in our EOQ formula guide and open-to-buy planning guide, or get set up with the Shopify and Linnworks installation guides.
Purchase Order Software — FAQs
What is purchase order software?
Purchase order software creates, sends, and tracks the POs you place with suppliers. Replenagise goes further than record-keeping: it forecasts demand per SKU, auto-calculates order quantities from reorder points, safety stock, and supplier lead times, and raises the finished purchase order directly into Shopify or Linnworks.
Can purchase orders be fully automated?
Yes. Replenagise can run your routine purchasing automatically — when a SKU hits its reorder point, a PO is generated with the optimal quantity, assigned to the right supplier, and raised into your platform. You review exceptions rather than building every order by hand.
Does Replenagise manage suppliers and lead times?
Yes. Each supplier holds its cost prices, currency, and lead time. POs are grouped per supplier automatically, and lead times feed the reorder-point calculation so orders are placed early enough to land before you run out.
What is the best purchase order software for small business?
For ecommerce sellers on Shopify or Linnworks, Replenagise is a strong fit: it automates the full loop from forecast to raised PO, includes supplier and lead-time management on every plan, and is priced by catalog size from $37.99/month — with a 14-day free trial.
