One shop is manageable — you know your renewal date and keep half an eye on the bill. Add a second or third site, sometimes with different suppliers left over from different openings, and it becomes very easy for at least one contract to quietly roll onto an expensive out-of-contract rate without anyone noticing.
Multi-site businesses often end up with a patchwork of contracts — different suppliers, different renewal dates, sometimes different rates for near-identical usage — simply because each site was set up separately. Nobody chose that patchwork on purpose; it’s just what happens when contracts are handled site by site rather than as a whole, often by whoever happened to be opening that particular branch at the time.
The more sites you add, the more renewal dates there are to track, and the easier it becomes for one to slip through. Some multi-site operators only discover a site has been on a deemed rate for months when they finally sit down and compare all their bills side by side — by which point it has usually cost several thousand pounds more than it needed to.
This comes up constantly with multi-branch salons, grocery shops, and pharmacies with more than one branch, but it applies to any business operating from more than one address — including franchise operators and businesses that have grown through acquisition, where inherited contracts are often the least reviewed of all.
Send us your sites’ current bills and renewal dates and we’ll build a single comparison across all of them, flagging any that are already overdue for a renewal check — at no cost. Once everything is mapped out, we can also keep tracking future renewal dates for you, so this doesn’t become a recurring admin job for whoever happens to have time for it.
