Top 7 Apps for Small Business

1. Evernote:
Evernote is the app for syncing notes across mobile and desktop devices. If you’re just starting out, you’re probably going to be bombarded with advice from every angle. Evernote serves as a great space in which to organize these nuggets of wisdom. Every Evernote user can use 2 GB per month to upload and organize notes. This version is free. The Business Premium account, which costs $5 per employee per month (or $45 per year), can be synced to your personal Evernote account. Evernote works on all devices and operating systems.
2. Dropbox:
Boasting about 300 million users, Dropbox is the most popular platform on which to store and share files on the cloud. Though Dropbox could probably benefit any small business, its services are especially useful for companies that have telecommuters and need a reliable way to share information. If you’re interested in seeing how much Dropbox would cost your small business, check out its quote tool. Dropbox offers free trials and works on all devices and operating systems.
3. ZenPayroll:

ZenPayroll streamlines the entire payroll process for employers. The service is paperless and automatically calculates all relevant income taxes. The app lets its users access their pay stub archives at any time, along with documents like state and federal payroll taxes. ZenPayroll works on all devices and operating systems and has a $25 monthly base fee, along with a monthly charge of $4 for your company’s first 10 users, and $2 for every employee after that.
4. Contactually:
Contactually lets you keep in touch with everyone, from teammates to former colleagues to prospects, with ease. Its mobile app is a cinch to use, too. You simply put your contacts into "buckets," and then decide how often you want to follow up with the people in each one. Contactually will do the rest, automatically creating follow-ups for you and letting you know the last time you spoke to the person in question. Use dynamic templates to make your holiday wishes, congratulations and follow-ups after meetings incredibly easy, while still retaining a human touch.
5. HelloSign:

Eliminate paperwork and having to sign, scan and email signed documents.
HelloSign makes it possible to sign forms and contracts from your tablet or smartphone. You simply save your signature and use it to sign documents and request signatures for up to 20 others to sign. When the document is fully executed, everyone gets a copy delivered to their inbox. See your documents progress with status notifications that keep you in the loop throughout the approval process.
6. Quip:
Quip enables you to collaborate with others on documents. The app is a dream for business users who need to work on drafts and edits in real time, as well as keep in touch with constant updates. As the company says, Quip makes it easy to cut down on email because work groups can be notified on mobile devices as projects evolve. The app also works with attachments and allows you to create and work on documents — even when you're offline.

7. Unroll.me:
There is nothing we hate more than a crowded email inbox filled with subscriptions. Thankfully, Unroll.me was created to fix that exact problem. Simply sign up with your email address and let Unroll.me find all of your subscriptions for you. Then easily scroll through and unsubscribe from the ones you'd rather never hear from again. Unroll.me will deliver one daily email with all of your subscriptions. You can also make sure the right emails break through all the noise and go directly into your inbox.
