Zilch vs Assent for Distributor Compliance

A customer asks for compliance information on 80 products. You have some declarations, your suppliers have the rest, and half the manufacturer part numbers do not match your catalogue. The order waits while your team becomes a document collection service.

Both Zilch and Assent address this problem. If you are comparing them, start with the work your business needs done and the evidence your customers accept.

Assent deserves a serious look where product material compliance, manufacturer declarations and complex parts catalogues drive the workload. Zilch is built around wholesale distributors answering buyer requirements across their business, suppliers and products, including sustainability information used in quotes and tenders.

There is meaningful overlap. A useful comparison should make that overlap clear rather than award either product a suspiciously convenient row of green ticks.

What Assent now offers distributors

Assent launched its Distributor Experience in August 2026. It connects distributor catalogues, supplier information and customer requests through the Assent Network.

Its published capabilities include importing large catalogues without a bill of materials, matching customer and manufacturer part numbers, reusing existing declarations and collecting missing information through supplier workflows. Dashboards show coverage and participation.

That changes the comparison. Describing Assent as software only for manufacturers would miss its current distributor offering.

Assent also offers Request Manager for handling incoming compliance and sustainability requests. Ask which parts of the proposed solution come with the Distributor Experience, which require another module and how they work together in your account.

What Zilch brings to the comparison

Zilch combines product documentation, supplier evidence, questionnaire automation and product sustainability data for wholesale distributors.

The practical goal is to reuse the information you hold across buyer requests. A factory audit should be connected to the supplier it covers. A product test report should be linked to the relevant SKU. An approved company policy should be available when the next buyer asks for it in different words.

Zilch then helps turn that information into customer responses and product reports. Sustainability data also supports comparisons between products when a salesperson needs to explain why one option is worth choosing.

That makes the evaluation broader than whether a platform can store a PDF. You are buying a way to get from an incoming request to a supported answer with less manual work.

The quick comparison below covers catalogue structure, incoming requests, supplier collection, material declarations, company questionnaires, sustainability outputs and the implementation work required.

Start with the type of evidence customers request

Some distributors repeatedly receive requests for substance declarations, regulatory reporting templates and compliance status across technical parts. Others spend more time answering questions about ethical sourcing, policies, insurance, factory audits, recycled content and product emissions.

Many do both. The proportions matter.

Take your last ten requests and record the information requested, the person who answered, the source documents used and the time spent. Include the requests you declined because gathering the evidence was too hard.

This produces a much better buying brief than a list copied from a software directory. It also prevents your most technically complicated request from determining the system you use for every ordinary one.

For each requirement, distinguish a document being present from a conclusion being justified. A platform may hold a declaration without establishing that it covers your exact product, market and current version of the requirement.

Test product matching with your awkward records

Product identity is often where a promising demonstration becomes a messy implementation.

A distributor may use its own SKU, a manufacturer code, a supplier code and a customer-specific code for the same item. A family of products may share a document while individual variants have different components or coatings.

Give both vendors a sample containing those problems. Include duplicate names, superseded products, missing codes and a document that only covers part of a range.

Ask the platform to explain why a document was linked to a product and how uncertain matches are reviewed. A high match rate is less useful if nobody can identify the false matches.

Also ask what happens when a manufacturer changes a part number. You need the history of the item and its evidence to survive the update.

Find out how useful the supplier network is for you

An established data network can shorten collection work when it contains the manufacturers and declarations you need. The relevant test is coverage of your suppliers and products.

Provide a representative supplier list and ask Assent to demonstrate what information can actually be reused. Check its currency, permitted use and applicability. A network-wide total does not tell you how much of your particular catalogue is covered.

Run the same practical test with Zilch's collection process. Which documents can be found from your existing records, and which need to be requested? How does the system follow up when a manufacturer does not respond?

For both, ask how a supplier can correct a mistaken product association and whether your team can see exactly what remains unresolved.

Follow a customer request all the way through

Use a real request rather than a vendor's demonstration file. Choose one with attachments, ambiguous wording and evidence you do not yet hold.

Watch the complete process:

• The request arrives and the relevant products are identified.
• Existing evidence is retrieved and checked for scope.
• Missing information is requested from the correct supplier.
• Unsupported questions remain visible for review.
• An authorised person approves the response.
• The final output fits the customer's required format.

The last point matters. A polished report is useful until a buyer insists on its own spreadsheet or portal. Ask each vendor to demonstrate the formats your customers actually send, including how uploads and browser forms are handled.

Check the sustainability work separately

The word sustainability can describe very different outputs. It might mean a supplier risk assessment, a substance declaration, an organisational emissions estimate or a carbon footprint for an individual product.

Ask what each platform produces, how it is calculated and what evidence supports it. If you want product comparisons for quotes, test a pair of products your sales team already recommends.

Check that the comparison uses equivalent units and a consistent calculation boundary. If one figure covers a single item and another covers a carton, the software has made a very fast mistake.

For Zilch, this is an important part of the commercial case: product evidence can help satisfy procurement and give salespeople more substance than a generic sustainability claim. Establish whether those outputs are valuable to your buyers before assigning them a financial benefit.

Compare the total operating cost

Get a written quote for your actual volume. Do not compare a published entry price with a configured enterprise proposal.

Include subscription fees, implementation, data migration, supplier engagement, regulatory modules, integrations, additional users and ongoing support. Ask how charges change when your catalogue or request volume grows.

Then estimate the work left for your team. If a system saves document retrieval time but requires substantial manual mapping every month, count that maintenance.

An illustrative calculation is straightforward. If your business handles 30 requests a month and removes 45 minutes of work from each, that is 22.5 hours returned to the team. Multiply by your loaded staff cost, then add implementation and review time. Keep possible revenue benefits separate until you can observe them.

Which businesses should shortlist each platform

Shortlist Assent when your requirements depend heavily on product material compliance, manufacturer declarations and network-based data reuse across a complex parts catalogue. Its distributor offering addresses exactly those workflows, so test it on representative products.

Shortlist Zilch when your wholesale team needs to answer company and supplier questionnaires, organise product documents and use sustainability evidence in customer-facing sales work. Bring a mixture of those requests to the demo.

If your requirements overlap, run the same trial with both. Measure time to an acceptable answer, unresolved gaps, reviewer effort and the ability to reuse the result the next time a buyer asks.

If you are still building the shortlist, our guide to 10 supplier compliance software platforms sets out where each option fits.

Bring the request that is holding up an order

The strongest demonstration starts with work you need finished. Ask the vendor to process a current request, using your products and your evidence, and show the human work that remains.
