Trade counters live and die by speed. A customer wants to know if you've got the part in stock, whether the order they placed on Tuesday has landed, or if the quote they were sent last week is still good. Increasingly, that conversation happens over WhatsApp rather than the phone, because it's the channel customers already use to send photos of a broken part or a product code lifted off an old label. Stitch, the WhatsApp business communication platform, works with trade counter and builders' merchant businesses to turn that existing WhatsApp habit into a properly managed, shared communication channel instead of a liability sitting on individual staff phones.
This guide walks through how to set up and run a shared WhatsApp inbox for stock enquiries, order status updates, and repeat trade customer messaging, based on how Stitch's trade counter customers actually use the platform.
Trade counter businesses have told Stitch directly that WhatsApp is already how they communicate with customers day to day: it's convenient for sending quotes, sharing images of parts or stock, and getting quick sign-offs before proceeding with an order. The businesses using it this way tend to have a high proportion of repeat trade customers who specifically prefer WhatsApp over email or phone calls.
The problem is what happens once that usage becomes standard practice without any structure behind it. Chat history becomes difficult to manage and store, and when an employee leaves the business, they can take their WhatsApp conversation history with them, along with the context of every customer relationship they'd been running through their own phone. That's the gap a shared inbox is built to close.
Before starting, a trade counter operation should have the following in place:
Your first decision is which number customers will message. For trade counters, this is typically the existing business landline that's already mapped to the shop or branch, set up as a shared team WhatsApp number used publicly. Using a number customers already recognise avoids the friction of asking them to save a new contact.
Onboarding starts with two forms: a customer order form and a WhatsApp profile form covering your logo, business description, and website. This is the information Meta and Stitch use to set up your business profile as it will appear to customers inside WhatsApp, so accuracy here matters. Once the forms are in, the next step is getting your account technically connected.
Stitch is added to the customer's Meta Business Suite to enable the connection between your number and the WhatsApp Business Platform. This is a necessary infrastructure step: the WhatsApp Business Platform is not the same as the consumer WhatsApp or WhatsApp Business apps most staff already have on their phones. It's an infrastructure layer that requires software such as Stitch's platform to provide centralisation, routing, and automation on top of it. With the connection in place, the number can be verified.
Verification happens through a one-time password (OTP) phone call made to the number you're setting up as your WhatsApp business number. This call delivers a six-digit code repeatedly, which Stitch uses to provision the WhatsApp number and bring the platform live.
Note: during this call, any IVR or menu system on that landline needs to be temporarily disabled so the code can actually be received. If your trade counter number normally answers with a menu ("press 1 for sales, press 2 for accounts"), flag this to whoever manages your phone system in advance so the OTP call isn't accidentally routed away.
Once the number is live, the shared inbox itself gets configured. Trade counter customers moving from personal-phone WhatsApp use to a managed setup can expect an inbox supporting up to six users under a standard package. Depending on the size of the operation, teams can be structured so that stock enquiries, order status questions, and general customer service land in the right place rather than in one undifferentiated stream. This structure is what makes it possible to actually action the next three use cases: stock checks, order updates, and repeat customer conversations.
A customer messaging to ask if a part is in stock no longer needs to interrupt whoever's serving at the counter or manning the phone. Because the WhatsApp conversation sits in a shared inbox rather than on one person's device, any available team member can see the enquiry, check stock, and reply, and the conversation remains visible to the business rather than disappearing if that staff member is busy or off shift. This directly addresses the chat history and staff turnover problem trade counters report: when the conversation lives in a shared, centralised inbox instead of an individual's phone, the business retains that history rather than losing it when someone leaves.
Sending quotes, images, and getting customer sign-off before proceeding is already core to how trade counter businesses use WhatsApp. A shared inbox keeps that workflow intact while adding accountability: any team member picking up a thread can see the quote that was sent, whether it was approved, and what happens next, without having to chase a colleague or dig through a personal phone. For businesses running a CRM alongside their trade counter operations, integration work is also in motion. One trade counter business working with Stitch has expressed interest in integrating Stitch's platform with its Business Pilot CRM specifically to bring chat history into a centralised platform, improve visibility, and streamline communication processes. That kind of integration is not yet a native, off-the-shelf feature and timelines depend on the complexity of the CRM connection, but it reflects the direction trade counters are pushing: chat history that lives in one place, tied to the customer record.
Repeat customers are a defining feature of the trade counter model, and a large share of them actively prefer WhatsApp as their communication channel. Once your shared inbox is live, use tagging and conversation notes to build a working history against these accounts, so any staff member picking up the thread has context on past orders and preferences rather than starting cold. This is where the shared inbox pays off most directly: repeat customers get consistent service regardless of which staff member is covering the counter that day, and the business keeps ownership of that relationship history rather than it being locked inside one person's phone.
The OTP verification call isn't going through. Check that any IVR, auto-attendant, or call menu on the number has been fully disabled before the call is placed. The code is delivered directly and repeatedly, and any automated menu intercepting the call will prevent it from being received.
Staff are still defaulting to personal WhatsApp for customer chats. This is the exact fragmentation problem a shared inbox is meant to solve. Revisit which number customers are being given at the counter and in marketing materials, and make sure it's consistently the shared business number rather than individual staff mobiles, so conversation history stays with the business. It is also important to ensure that how UK GDPR and Data Residency Rules Apply to WhatsApp Business Messaging is understood, as using personal devices for business data can create compliance risks.
You need chat history inside your CRM and it isn't there yet. Native CRM integration timelines vary by system and complexity. Trade counter customers working through this with Stitch have been told the integration is being worked on closely with the CRM provider, with the expectation that chat history will become accessible within the CRM once complete, though the exact timeline isn't fixed.
A shared WhatsApp inbox turns a channel your trade counter customers already prefer into a properly managed part of the business rather than a collection of individual staff conversations at risk of walking out the door with an employee. By onboarding through Stitch, connecting your existing business number, and structuring your inbox around stock enquiries, order updates, and repeat customer relationships, you keep the speed and convenience of WhatsApp while gaining the visibility and continuity a growing trade counter operation needs. If your business is currently juggling quotes, sign-offs, and stock checks across personal phones, the next step is scoping onboarding with Stitch and identifying which number and team structure fits how your counter actually works.
