B2B Software Companies: Vendor, Reseller or Integrator?

A B2B software company is any firm that sells software or software-related work to businesses. When you read a proposal, it helps to ask a simple question first: which kind of company is this? The answer changes who supports you, who holds your data and who you call.

The vendor

The vendor makes and runs the product. It writes the code, operates the servers and decides what the software can do. Buying directly from a vendor means you have one party to hold accountable, and you can usually speak to the people who can fix a product problem.

The reseller

A reseller sells someone else's product, often bundled with services, local support or billing in your currency or terms. Resellers can be useful when you want a single point of contact or help with setup. The important question is who supports what. A reseller may answer questions about how to use the product, while only the vendor can change it.

The marketplace

A marketplace is a catalog where buyers can find and sometimes purchase software. Marketplaces make comparing and paying easier, particularly when your organization has pre-approved purchasing channels. Listing in a marketplace is not the same as being reviewed by it, so treat it as a convenient shop window, and read the vendor's own terms.

The integrator or consultancy

An integrator configures software for your needs, connects it to other systems and trains your staff. Their output is time and expertise, not a product. This is valuable for complicated setups, though it adds cost and a dependency on the people who did the work, so ask for documentation when they finish.

The software company that is also a services company

Some vendors sell both a product and professional services. That can be helpful when you need help, but pay attention to whether services are hiding product gaps. Ask which parts of the work will become standard product features and which will remain custom.

A decision aid

• If you want the most direct support on the product itself, buy from the vendor.
• If you want bundled services or local billing, consider a reseller, and ask who handles product bugs.
• If your organization buys only through approved channels, a marketplace may fit.
• If your setup is complicated, hire an integrator, and request documentation.

When this distinction does not matter

If you are signing up for a simple tool with a credit card, the vendor is the seller and there is nothing to untangle. The question becomes important when contracts, support promises and money pass through more than one party.

Example: three quotes for one order system

A small manufacturer wants a system for tracking orders. It finds the vendor's own website, a reseller offering the same product with local training, and a consultancy proposing a custom build. The reseller's quote includes setup and a monthly support fee. The vendor's quote has only the software. The consultancy's quote is an estimate of hours.

Laying the three side by side, the manufacturer realizes it is not comparing prices for the same thing. The vendor's price buys a product, the reseller's price buys a product and a person, and the consultancy's price buys a person and a result. Only then can the real comparison begin.

Questions to ask each type of company

• Of the vendor: what happens to my data if I leave, and how do you handle product feedback?
• Of the reseller: which problems can you solve yourselves, and which do you escalate?
• Of the marketplace: who is responsible if the listed product is withdrawn?
• Of the integrator: what will you document, and who maintains it later?

How the type changes the contract

Who signs matters. If you sign with a reseller, your rights over the product may depend on the reseller's own agreement with the vendor. If you sign with the vendor, you hold the direct relationship. Ask which agreement applies to the software, the services and the data, and keep the answer in writing.

How to ask for the right documents

When you evaluate a company, ask each type for different papers. From a vendor, request the terms of service, privacy policy, a description of security practices and the product's documentation. From a reseller, ask for its agreement with the vendor, in so far as it affects you, and its own support terms. From a marketplace, ask what review, if any, it applies. From an integrator, request a statement of work, an estimate and a plan for documenting the result. Having the right documents on file makes later disputes simpler to resolve.

Choosing between a direct purchase and an intermediary

A direct purchase gives you one relationship and a shorter line to the people who build the product. An intermediary can give you convenience, local support or bundled services. A fair rule is to go direct when the product is simple and you can manage setup yourself, and to consider an intermediary when you need help the vendor does not provide. In either case, ask who is accountable for each part, and get it in writing before the first invoice.
