The log tools stop at the list
AutoSpecs drafts the register and publishes it. Procore builds the log and routes it. Neither goes looking for a cut sheet, and neither assembles anything. The list is the deliverable.
Submittal software, compared
Six products describe themselves with nearly the same sentence. They finish in four different places. This page sorts Autodesk AutoSpecs, Procore Submittals, Bluebeam, Submittal.com, BuildSync and SubPro by the object you are holding when each one is done.
The category splits on one question
Not which product is best. What it produces when it finishes running. There are four answers on the market, and buying the wrong one is how a team ends up with excellent software and the same workload.
- A list. Every item the project manual requires, and who owes it. This is the submittal log, also called the register.
- A workflow. Somewhere to route items, hold reviews, and see who has been sitting on what.
- A review. A report on a submittal package somebody already built, checked against the project manual.
- The submittal package. Cover sheet, transmittal, manufacturer product data in spec order, in the format the general contractor requires.
Where each product starts and stops
Verified against each vendor's own documentation on 20 September 2026. Rows describe what a product does, not how well it does it.

Read the first three rows together
Taken one at a time, several products can claim a row. Taken together, the first three rows are the whole job: read the project manual, go and find the manufacturer documents, build the submittal package. SubPro is the only product in this table that does all three across every division.
The assembly tools need you to read first
Submittal.com has a real library and real assembly behind it, and says so plainly: the log is semi automated and you take off the project manual yourself. The reading stays your job.
The closest competitor is bounded by trade
BuildSync reads, sources and assembles, which is the same shape. Its package generation covers mechanical, electrical and plumbing equipment. Division 08 door hardware and Division 09 finishes are outside it.
SubPro does all three, everywhere
Every division of the project manual, read for your scope. The manufacturer documents pulled and matched to the row. The submittal package assembled behind your transmittal, as one PDF.
What you get that the table has no row for
A comparison table can only ask whether a product does a thing. These are the parts that decide whether the output is worth sending.
Every row cites its spec page
Each requirement carries the page it came from, one click away. Your reviewer checks a citation instead of trusting a machine, which is the difference between a draft you can approve and one you have to rebuild.
A library already on file
More than 400 indexed manufacturers and over 16,000 documents, each entry keeping its source. When the project manual names a manufacturer, the literature is usually already here rather than somewhere on a supplier site.
It tells you where it is unsure
Ambiguous language, a possible duplicate, a product named without a maker, a substitution that needs a decision. Those rows arrive flagged for a person rather than stated as flatly as everything else.
A person reviews before you receive it
Nothing reaches you straight out of the machine. Review is part of the product rather than an added line on the invoice, and it is why the package arrives in a state you can send rather than a state you have to check line by line.
Ask the project manual a question
Chat with the book or the log in plain language and the answer comes back with the page attached. The 1,200 page problem becomes a lookup.
Your documents do not stay
Project files come out of the system once processing finishes, and nothing you send is used to train a model. The data handling page sets out the mechanics.
The word submittal means two different jobs
Most of the confusion in this market comes from one noun doing two jobs. Which one you owe decides what a tool has to produce for you. Most products in this category pick a side and stay there. A few, SubPro among them, do both halves, which is why the same product can serve a general contractor issuing the register and a trade contractor building what goes back.
If you owe the list
- The general contractor or construction managerA complete, defensible register off a 1,200 page project manual, issued to every trade on the job, then the incoming submittal packages to route and track.
- Your problem is readingSomebody has to work through every section and pull out what is required. A log generator is the correct purchase.
- Then routingOnce the register exists, the work becomes status and visibility across reviewers, which is what a workflow platform is for.
If you owe the contents
- The trade contractorNinety rows with your name on them, each one needing an actual document before anybody can review it.
- Your problem is sourcing and assemblyFind the product data, confirm the manufacturer against what the section allows, put it in order, cover it, transmit it.
- The log was the easy halfA register tells you what is owed. It does not reduce the hours between knowing and sending.
Where SubPro sits
SubPro reads the project manual and builds the submittal package. Every row carries the spec page it came from, so the person reviewing checks a citation rather than trusting a machine, and a reviewer goes through the package before it reaches you.
- It tracks its own work through closeout. Submittals go out from the app, the response is recorded against the row, waiting rows count days out, and revisions keep their history. Schedule, lead times, addenda comparison and closeout live on the same record.
- It is not the general contractor's system of record. Where the job runs on a platform, the submittal still goes into that platform, and SubPro exports Excel so the record carries across rather than being retyped.
- It works from either side of the handoff. A general contractor uses it to turn a project manual into the register and to hold the record through closeout. A trade contractor uses it to build the submittal packages that register asks for. Same reading of the same book, two different things owed.
- Every row cites its spec page. Review is a verification task instead of an act of faith, which is the only way an assembled package is worth more than one a person built.
- Your documents do not stay. Project files come out of the system once processing finishes, and nothing you send is used to train a model.
The longer arguments
Three articles sit behind this grid, each one taking a single question further than a table cell can.
Sorted by what you are holding at the end
The category read as four finish lines: a list, a workflow, a review, or the submittal package. Where the money gets wasted is someone buying the first and believing they bought the fourth.
Choosing an alternative to a log generator
AutoSpecs drafts the register, and does it well. Most people searching for an alternative do not want a different log generator, they want a different step of the job.
What Procore routes, and what you still build
Written from the subcontractor's chair. Procore tracks the submittal and shows everyone who is holding it. It does not go and find the product data for Division 08.
Submittal software comparison FAQ
Which submittal software builds the actual submittal package?
Submittal.com and SubPro produce the assembled submittal package. Autodesk AutoSpecs produces the submittal log, which is the list of what is owed. Procore builds the log from spec sections, then routes and tracks it. BuildSync builds and checks, within mechanical, electrical and plumbing equipment. Choosing between them starts with whether you owe the list or the contents.
Is SubPro a replacement for Procore?
No, and they are not the same shape. Procore is the system of record for the whole job, and it sells to specialty contractors as well as general contractors. SubPro is the subcontractor's own record: it reads the project manual, builds the submittal package, then sends it, records the response, counts days out, and carries revisions and closeout. Where the job runs on Procore the submittal still goes into Procore, and SubPro exports Excel so the record carries across.
What is the difference between a submittal log and a submittal package?
The log, also called the register, lists every item the project manual requires and who owes it. The submittal package is the document you send for review: cover sheet, transmittal, and the manufacturer product data in spec order. Log tools read the project manual. Package tools assemble the deliverable.
How does SubPro compare to Autodesk AutoSpecs?
AutoSpecs reads the project manual and drafts the submittal log, then publishes it into a project management platform. SubPro reads the project manual too, and does not stop at the list: it builds the submittal packages, sends them, records the responses, and carries the record through addenda and closeout. A general contractor can use either to get the register. Only one of them also builds what goes back.
