ERP to Ecommerce Integration in Australia
Your ERP knows what you actually have, what it costs and who owes you money. Your online store knows what customers just bought. Between the two sits a person with a spreadsheet, copying orders down and stock levels up, five days a week.
We build the two-way connection properly: orders and customers flow from the store into the ERP, stock levels, pricing, product data and dispatch confirmations flow back out. Built for the parts that trip up standard connectors, including multiple warehouses, wholesale price tiers, kits and bundles, part shipments, credit notes and GST that has to reconcile to the cent.
Realistic ROI
Why ERP to Ecommerce Is Harder Than It Looks
Both systems hold customers, products and orders, which makes them look easy to join. They mean slightly different things by all three, and that is where the work is.
Your product catalogue is not one catalogue
The ERP holds a part number, a cost, a supplier and a unit of measure. The store holds a title, images, variants, categories and a search description. They overlap on maybe half the fields. A working integration decides which system owns which attribute, so marketing can rewrite a product page without anyone fearing it will break the picking process.
Pricing is rarely one number
Most Australian wholesalers run customer specific pricing, quantity breaks, promotional prices with start and end dates, and different rules for retail against trade. Standard connectors typically push one price field. Getting this right means the store shows the logged in customer the price your ERP would actually invoice them, which is usually the whole reason for connecting the two.
Orders do not stay tidy after they are placed
A real order gets partially shipped from two warehouses, has a line cancelled, picks up a freight charge that was estimated at checkout, and sometimes comes back as a return three weeks later. The integration has to keep the store, the customer and the ERP in agreement through all of that, not just at the moment of purchase.
The numbers have to reconcile to the cent
Web orders end up as revenue in your accounts, which means GST treatment, rounding, freight, discounts, gift cards and payment fees all have to post the way your accountant expects. An integration that is out by cents per order becomes a monthly reconciliation task, which defeats the purpose of building it.
What Moves Between ERP and Store
Six flows. Most businesses need all six eventually, and they are usually built in this order.
Orders into the ERP
Every web order lands in the ERP as a proper sales order within minutes, with the right customer, the right price, correct GST, freight and discounts, and a reference back to the store order number. Payment method and settlement details carry through so finance can reconcile without opening the store admin.
Stock levels out to the store
Available quantity flows from the ERP to the store, per warehouse where that matters, with a configurable buffer so a shop floor sale and a web sale never race each other to the last unit. Committed and on order quantities can be surfaced separately for trade customers who need lead times.
Pricing and promotions
Price lists, customer specific pricing, quantity breaks and dated promotions flow from the ERP so the logged in customer sees the price they will actually be invoiced. Retail and trade pricing are handled as separate rules rather than a single overwritten field.
Product and catalogue data
New products, part numbers, units of measure, weights and dimensions flow from the ERP, while titles, images, descriptions and categories stay owned by the store. Each attribute has one owner, so a marketing edit and an operations edit never overwrite each other.
Customers and accounts
New web customers are created in the ERP, and existing trade accounts are matched rather than duplicated, using a combination of email, ABN and account code. Credit limits and account status can gate what a trade customer is allowed to order online.
Fulfilment and returns back to the store
Dispatch confirmations, tracking numbers, part shipments, backorders, cancellations and credit notes flow from the ERP back to the store and into the customer notification. This is the flow most often left out, and the one that removes the most inbound where is my order calls.
Before and After a Proper ERP Ecommerce Integration
| Task | Traditional | With Yes AI | Notes |
|---|---|---|---|
| A web order arrives | Exported and keyed in each morning | In the ERP within minutes | Same day dispatch cut offs become realistic because picking is not waiting on a morning data entry run. |
| The last unit sells twice | Oversold, apology and refund | Availability updated near real time | A safety buffer per product line covers the seconds between a shop floor sale and the store update. |
| A trade customer logs in | Shown retail price, then adjusted | Sees their contract price | Customer specific pricing and quantity breaks come from the ERP rather than being maintained twice. |
| An order ships from two warehouses | Store still says processing | Part shipments and tracking sync | The customer gets two tracking notifications instead of one silence and a phone call. |
| A product price changes | Updated in ERP, forgotten online | Pushed from the owning system | Stops the classic problem of the website advertising a price you no longer sell at. |
| A customer returns an item | Credit note raised, store unaware | Credit and stock flow back | Returned stock re-enters availability automatically instead of sitting unlisted in a returns bay. |
| End of month reconciliation | Two days matching store to ledger | Posts correctly as it happens | GST, freight, discounts, gift cards and payment fees mapped to the accounts your accountant expects. |
| Black Friday triples volume | Imports back up, staff work late | Paced, queued and retried safely | Load tested ahead of peak so rate limits are managed rather than discovered on the day. |
How We Keep an ERP Integration Safe
Clean the product data before connecting
The most common cause of a failed ERP to store project is not the integration, it is duplicate part numbers, inconsistent units of measure and products that exist in one system and not the other. We audit and reconcile the catalogue first, because connecting two messy catalogues just distributes the mess faster.
One owner per field, written down
The ERP owns cost, part number, weight and available quantity. The store owns title, images, description and category. Price ownership depends on your business and is decided explicitly. Without this agreement, an operations update and a marketing update will overwrite each other and nobody will be able to say which is correct.
Every write is safe to repeat
Orders are the highest risk object to duplicate, because a duplicate order can be picked and shipped before anyone notices. Each order carries a stable reference so a retry after a timeout updates the existing record rather than creating a second one. The same applies to invoices, credits and stock adjustments.
GST and rounding agreed with your accountant
We confirm how tax inclusive and exclusive pricing, freight, discounts, gift cards, surcharges and payment fees should post before go live, and run a parallel reconciliation for the first month. Getting this wrong is not a technical problem, it is a business activity statement problem.
Tested against peak volume, not average
ERP and ecommerce APIs both enforce rate limits, and the season when volume triples is exactly the season when a stalled integration costs the most. We test at multiples of your current volume, pace and queue requests, and confirm the backlog drains cleanly rather than silently dropping orders.
Least privilege access and audit logging
Each connection uses a dedicated service account with only the permissions it needs, never a staff member’s login, so someone leaving the business does not break the integration. Every synced record is logged for audit, and personal information is handled under the Privacy Act 1988 and the Australian Privacy Principles.
How Yes AI Delivers ERP Ecommerce Integration
Data and flow audit first
We review your catalogue, customer records and pricing structure, map every flow you need in both directions, and identify what has to be cleaned before anything is connected. You get a prioritised plan and a fixed price, and the audit findings are useful even if you build elsewhere.
Built against your real edge cases
Kits and bundles, multiple warehouses, backorders, part shipments, trade pricing, credit notes, freight rules. We build and test against your actual awkward records rather than a tidy sample, because those cases are where the manual work you are paying for actually lives.
Parallel run before you rely on it
The first flow goes live alongside your existing process for a short period so you can compare the two and confirm the numbers agree before switching off the manual work. Nobody should have to take an integration on trust at end of month.
Monitored and maintained through peak
Same day alerting on failures, load headroom checked before seasonal peaks, and vendor API changes absorbed under the managed fee. When your ERP or store platform updates, keeping the connection working is our job.
Our ERP Ecommerce Integration Rollout
Five steps. Most businesses have orders flowing into the ERP within four to six weeks.
Audit the data and map the flows (week 1)
We review the product catalogue, customer accounts and pricing structure in both systems, list every flow you need in each direction, and flag the data that needs cleaning before it can be trusted.
Agree ownership and tax treatment (week 1 to 2)
Field by field ownership between ERP and store, plus how GST, freight, discounts and payment fees should post. Signed off by you and, where it matters, by your accountant before any build starts.
Build orders in and stock out (week 2 to 4)
The two flows that remove the most manual work are built first, against official APIs, and tested on a copy of your real data including the awkward historical records.
Parallel run, then switch over (week 4 to 6)
The integration runs alongside your manual process while we compare results and tune matching, buffers and exception rules. Once the numbers agree, the manual process stops.
Extend and maintain (ongoing)
Pricing, catalogue, customers and fulfilment flows follow, then we monitor everything, alert same day on failures and prepare capacity ahead of seasonal peaks.
