OmniDocAfter downloading signed contracts in bulk, how do you verify each copy with the original?
After downloading the contract in bulk for online signing, how to compare each signed document with the original one by one, confirming that the content has not been altered, the signature pages are complete, and the document has no serial numbers? The article provides steps and checklists for matching contract numbers, verifying with PDF comparison functions, and manually reviewing key clauses.
Key points of this article
- After batch downloading, don’t just look at the file name. Match each signed copy with the corresponding original according to the contract number to avoid aliasing.
- Use the PDF comparison function to compare the originals one by one and quickly find differences in content such as text, amounts, dates, etc.
- Scanned documents or signed documents whose text cannot be selected should be OCRed first and then compared, otherwise the comparison results will be unreliable.
- The comparison tool can only find text differences. Whether the signature page is complete and whether the signature is clear still needs to be manually checked page by page.
- When discrepancies are found, keep the original and signed copies first, record the location of the discrepancies, and then confirm with the other party. Do not overwrite the documents directly.
After a contract is signed online, it is common to get a dozen or even dozens of signatures at one time. People usually download them all into a folder first and then archive them directly. But if one of the documents has a serial number, is missing a page of signature, or has a number changed in the text, it will be too late until a dispute arises. After the contracts are signed online and downloaded in batches, checking each copy with the original is the last step to prevent this risk before filing.
This article is written for legal, administrative, financial, and business leaders who need to handle multiple contracts. After reading, you'll know how to find the corresponding original for each signature, how to use the PDF comparison feature in the OmniDoc desktop client to compare each copy, and which content needs to be reviewed manually. The methods in this article do not rely on any specific software; if you switch to other tools, the approach is also universal.
How to verify signed documents downloaded in bulk with the originals one by one? In short, a conclusion
Direct conclusion: First, pair the signed documents with the originals one by contract number, then use the PDF comparison function to compare the main text one by one, and finally manually check the signature page and key clauses. The comparison function is responsible for identifying differences at the text level, while the human function is responsible for confirming signatures and business judgments—both are indispensable.
| Your situation | Recommended recipe | reason |
|---|---|---|
| The contract is a text version PDF, signed only with a signature | Use the comparison function to compare the original, focusing on the difference marks | Can directly see whether the text and numbers have been altered |
| The signature is a scanned picture, and text cannot be selected. | First do OCR to recognize text, and then compare | The image lacks a text layer, so the direct comparison results are incomplete |
| Download dozens of copies at a time with similar file names | Create folders based on contract numbers, pair them one by one, and then compare them | Avoid putting client A’s signature and client B’s original copy together |
| The contract contains the amount, date, and default clauses | After comparison, these key paragraphs are manually reviewed | Machines can only report text differences; the meaning of business needs to be judged by humans |
| The original has a revised version | First confirm which version you signed, and then select the corresponding original to compare. | Compared with the wrong version, the result is meaningless |
Before you start: Confirm these points first
Taking a few minutes to do the preparation before starting the comparison can avoid a lot of rework.
- Confirm the final version of each original document. The signed version must be the final one. If the contract has gone through multiple rounds of revisions, you must first find the PDF that was attached when signing from the email or contract system as a baseline for comparison. Otherwise, the difference may only be the difference before and after the revision.
- Confirm the type of signature. Try using the mouse to select a text section in the PDF. If you can select text, it means it is a text version; if you cannot select, it means it is mostly a scanned copy or picture version. The two situations are handled differently, as will be explained later.
- Prepare a list of contract numbers. When batch downloading, the file name is often automatically generated by the system. Listing the contract numbers and customer names in a table and corresponding them one by one is more reliable than relying solely on file names.
- Keep an original backup. Do not rename the downloaded signature and overwrite it directly. During verification, only the copy operation is performed, the original file remains unchanged, and if there is a problem, it can be traced back.
- Prepare the installation environment. Comparison, OCR and other functions are in the OmniDoc desktop client. It can be downloaded from download.omnidoc.top and supports Windows, macOS and Linux.
Steps to compare signed documents with original documents one by one in OmniDoc desktop
The following steps are for a contract, and the whole batch of documents can be repeated according to the same process.
- Open the OmniDoc desktop client and enter the PDF editor. this is where comparison, OCR and other functions are located.
- deal with the scanned parts first. if the first step is to confirm that the signature is a scanned picture, perform OCR recognition on it so that the text can be selected and compared. After the identification is complete, proceed to the next step.
- Select the comparison function and load the original and the signature respectively. if two documents are a pair of the same contract number, check the file name again before loading.
- View the differences in the comparison results. look at the differences in text, tables and figures one by one. Usually only the signature or date will be added in the signing process, and if there is a change in the text of the text, it needs to be recorded emphatically.
- check the amount, date, name of the parties and time limit paragraph by paragraph. if these contents make mistakes and have a great impact, they should be manually confirmed with the original. We should not just look at whether the comparison tool reports "no difference".
- check the signature page page by page. make sure that each location that needs to be signed has a signature or seal, the page number is not missing, and the signature is not blocked.
- record the results. * mark "checked" or "discrepancy" on the contract number list, indicate the page number and location where there are differences, and then move on to the next one.
- all checked and filed. put the signatures that have passed the check into the file directory according to the contract number, and keep the original download documents and check records.
# check item by item after completion
After each signature has been checked, it is recommended to go over the following inspection items.
| Check item | What do you think? | What if there's a problem? |
|---|---|---|
| Whether the document corresponds to the contract number one by one | Open the signature and check the contract number list to see if the number and customer name are the same. | Find the correct original and re-compare, and remove the mismatched files separately. |
| Are there any unconfirmed changes to the text? | View the text differences in the comparison results and focus only on the text, tables and numbers | Keep two documents and screenshots of differences, and confirm with the signatory whether it is a valid modification. |
| Is the amount, date and time limit consistent? | Check key figures and dates item by item against the original | Stop archiving immediately, contact the other party to confirm, and re-sign if necessary |
| Is the signature page complete? | Flip through the pages and make sure that each signature location has a signature or seal | If there is a lack of pages or signatures, ask the other party to make up for it. Don't add it yourself. |
| Whether the number of pages is the same as the original | Compare the pages of the two documents | Different pages indicate that there may be additions and deletions, and you need to find differences page by page. |
| Is the result of OCR recognition reliable? | Spot check the identified words in several places and check them with the pictures | The identification of errors is based on the picture, and do not directly use it as a basis before manual correction. |
Both OCR and comparison functions have errors in identification or comparison, so the key content still needs to be manually reviewed and cannot rely entirely on the conclusions given by the tool.
# Core comparison
| Check mode | An appropriate situation | Major limitations |
|---|---|---|
| Page by page comparison with the artificial naked eye | A small number of copies and pages | Too many copies take a long time, and it is easy to miss minor changes. |
| PDF comparison function plus manual review | The text version of the contract has more copies. | The effect on scanned parts is limited, so we need to do OCR first. |
| Just look at the file name and the number of pages | Hardly suitable as a basis for verification. | Unable to find that the text has been altered and cannot be used for archival confirmation |
# frequently asked questions (FAQ)
1. The comparison results show that there is no difference, is it possible to file?
Not necessarily. The comparison function mainly depends on the changes of the text layer, whether the signature page is complete, whether the seal is clear, and whether the recognition of the scanned parts is accurate, it also needs to be checked manually. It is suggested that the key terms should be compared with the original.
2. The signature is to scan the picture, what if the comparison function is not available?
First do OCR recognition of the signature so that the text can be selected, and then compare. After identification, you still have to spot-check key numbers and dates, because OCR may have misrecognition.
3. Download dozens of copies at a time, how to avoid mismatching documents?
It is recommended that you first set up a folder according to the contract number, and then compare each signed copy and the corresponding original in the same folder. After the check is completed, tick the list one by one to avoid omission.
4. If you find any changes in the text, what should you do with it?
First keep the screenshots of the two documents and the different locations, and do not modify or overwrite them yourself. Then confirm with the signatory whether the change has been agreed. If there is no consent, the filing shall be suspended and dealt with in accordance with the internal process of the contract.
5. The contract is initiated by signing online, how to ensure that the original sent and signed are the same?
When initiating and signing, the PDF version number and file name issued shall be retained, and the signed document shall be compared with it. OmniDoc's signature request function can send PDF to others for online signature, and confirm the version to be signed before launching, which can reduce the trouble of later comparison.
# Summary
After the contract is signed online and downloaded in bulk, the focus of the check is to make sure that each signed copy is consistent with the corresponding original, the signature page is complete, and the key terms and conditions remain unchanged. Pairing according to the contract number, comparing it one by one with the comparison function, and then checking it manually, this process is suitable for most volume contract scenarios.
