Peak season is closer than it looks. Black Friday lands on 27 November, Cyber Monday follows on 30 November, the Christmas rush runs right up to the final delivery dates in December, and the post-Christmas sales start on Boxing Day and carry on into January.
That is two months of sustained high volume, and it starts in seven weeks. For most e-commerce businesses, now is the last realistic window to get a new integration scoped, built, tested and running before the busiest stretch of the year begins.
Peak trading puts more pressure on your systems than any other point in the year. Many retailers introduce a change freeze from early to mid November, locking down their technology so nothing breaks when trading is at its busiest. Projects that have not gone live by then usually wait until January, by which point the post-Christmas sales and returns are already underway.
Seven weeks is enough time to prepare, but not enough to delay. Work through the checklist below now, and each stage gets the attention it needs.
List every system involved in taking, fulfilling and accounting for an order: your online store, marketplaces, accounting or ERP software, warehouse and couriers. Then identify where data is still moved by hand. Each manual step is a point where volume will cause delays or errors.
Decide which systems need to connect and what data needs to move between them, such as orders, stock levels, customer records and payments. Clear scope now keeps the build focused and avoids surprises later.
Aim to have your integration built ahead of any change freeze. Starting in November squeezes every stage that follows.
Run the integration with real orders, stock levels and customer records. Testing at realistic volumes shows how your systems will cope when Black Friday traffic arrives.
Run live in the weeks before Black Friday, so any issues surface while there is still time to fix them, not in the middle of your busiest weekend.
Black Friday and Cyber Monday are only the start. Customers expect accurate stock information and fast delivery right up to the last Christmas order dates, and the post-Christmas sales bring another surge of orders alongside returns and year-end reconciliation. Make sure your processes can handle all of it.
If your online store, accounting software, warehouse and marketplaces do not share data automatically, every order means manual work. Orders are re-keyed into your accounts, stock levels are updated channel by channel, and payments are reconciled by hand.
Every manual data entry point introduces the risk of human error, from simple typos to misplaced copy-and-paste values. During high-volume trading, when teams are rushed, these errors compound rapidly. Beyond the direct expense of replacing misrouted or incorrect orders, customer dissatisfaction from fulfillment errors damages your brand's reputation at the most crucial time of year.
At normal volumes, that is inefficient. Across peak season, it becomes a bottleneck. The risks are familiar: overselling items that are out of stock, delayed dispatch, errors in your accounts, and teams pulled away from customers to chase data.
An integration that goes live now supports the whole stretch from Black Friday to the January sales. It also means you go into the new year with processes that scale, rather than a backlog of manual fixes.

Seven weeks is enough time to get an integration live before peak season, but only if you start now. Wait much longer and the choice becomes a rushed launch or another season of manual workarounds.

Peak season starts with Black Friday on Friday 27 November 2026 and Cyber Monday on 30 November. It continues through the Christmas rush and into the post-Christmas sales, which begin on Boxing Day and run into January.
Not if you start now. Early October leaves time to scope, build and test an integration before most retailers freeze changes in November.
