# Which module do I need

_Trackline, Consigne or SmartCheck: which one solves what you have in front of you._

**Responde a:** difference between trackline consigne and smartcheck · which module do i use to sign · what each part of the platform does · do i need to request documents or sign them

The three modules do different things with the same kind of material. The question that separates them is simple: is the document missing, does it need signing, or do you need to prove it existed?

| If what you need is… | Module | Example |
| --- | --- | --- |
| Someone to send you something you do not have | Trackline | Asking a supplier for their insurance and certificates |
| Someone to sign something you already have | Consigne | A contract, an amendment, a consent form |
| To prove something existed and said this | SmartCheck | A report, photos of a delivery |

## Using two is normal

Supplier onboarding starts in Trackline — you ask for their paperwork — and ends in Consigne — they sign the agreement. You do not have to choose: they chain together inside the same case.

## The commonest confusion

"I have a contract I want signed and I also need them to send me their insurance." That is both things: Consigne for the signature, Trackline for the insurance, in the same process.

> [!NOTE]
> If in doubt, start with whatever is most urgent. All three share the same contacts and the same documents: nothing you do in one has to be redone in another.

**Do they have to be bought separately?**

They share the account, contacts and balance. They are not isolated products.

**Can I use only one?**

Yes, many people start with one and add the others when they need them.

**Can a document signed in Consigne be certified?**

The signature already carries its certified date; certifying it separately is unnecessary.

## Ejemplos

**A company wants subcontractors to sign an agreement and also send documentation.**

- Builds a process that requests the paperwork
- Adds signing the agreement as the final phase

→ The subcontractor does it all from one link, without knowing two modules are involved.

**All that is needed is for a hundred suppliers to keep their paperwork current.**

- Sets up the request process and lets it chase on its own

→ It is solved with one module and no decision about the other two.

**A document must be signed with someone outside and there is nothing else to request.**

- Sends the document for signature and follows each signer's status

→ The signature closes without building a document process around it.

**Proof is needed that something existed on a given date.**

- Seals the document and keeps its dated trail

→ The proof stops resting on anyone's word.

**A company does not know where to start and wants to try all three at once.**

- Picks the process that consumes most time today
- Starts with the module that covers it

→ The first result arrives before anything permanent is decided.

**You start with one module and months later need another.**

- Adds the second over the same files

→ Nothing already running has to be moved.
